`arg`	Ath LogicSig argument
`balance`	balance for account A, in microalgos. The balance is observed after the effects of previous transactions in the group, and after the fee for the current transaction is deducted. Changes caused by inner transactions are observable immediately following `itxn_submit` params: Txn.Accounts offset (or, since v4, an available account address), available application id (or, since v4, a Txn.ForeignApps offset). Return: value.
`base64_decode`	decode A which was base64-encoded using encoding E. Fail if A is not base64 encoded with encoding E Warning: Usage should be restricted to very rare use cases. In almost all cases, smart contracts should directly handle non-encoded byte-strings. This opcode should only be used in cases where base64 is the only available option, e.g. interoperability with a third-party that only signs base64 strings.
`bitlen`	The highest set bit in A. If A is a byte-array, it is interpreted as a big-endian unsigned integer. bitlen of 0 is 0, bitlen of 8 is 4 bitlen interprets arrays as big-endian integers, unlike setbit/getbit
`bsqrt`	The largest integer I such that I^2 <= A. A and I are interpreted as big-endian unsigned integers
`btoi`	converts big-endian byte array A to uint64. Fails if len(A) > 8. Padded by leading 0s if len(A) < 8. `btoi` fails if the input is longer than 8 bytes.

`concat`	join A and B `concat` fails if the result would be greater than 4096 bytes.
`divmodw`	W,X = (A,B / C,D); Y,Z = (A,B modulo C,D) The notation J,K indicates that two uint64 values J and K are interpreted as a uint128 value, with J as the high uint64 and K the low.
`divw`	A,B / C. Fail if C == 0 or if result overflows. The notation A,B indicates that A and B are interpreted as a uint128 value, with A as the high uint64 and B the low.
`ecdsa_pk_decompress`	decompress pubkey A into components X, Y The 33 byte public key in a compressed form to be decompressed into X and Y (top) components. All values are big-endian encoded.
`ecdsa_pk_recover`	for (data A, recovery id B, signature C, D) recover a public key S (top) and R elements of a signature, recovery id and data (bottom) are expected on the stack and used to deriver a public key. All values are big-endian encoded. The signed data must be 32 bytes long.
`ecdsa_verify`	for (data A, signature B, C and pubkey D, E) verify the signature of the data against the pubkey => {0 or 1} The 32 byte Y-component of a public key is the last element on the stack, preceded by X-component of a pubkey, preceded by S and R components of a signature, preceded by the data that is fifth element on the stack. All values are big-endian encoded. The signed data must be 32 bytes long, and signatures in lower-S form are only accepted.
`ed25519verify`	for (data A, signature B, pubkey C) verify the signature of (“ProgData” \|\| program_hash \|\| data) against the pubkey => {0 or 1} The 32 byte public key is the last element on the stack, preceded by the 64 byte signature at the second-to-last element on the stack, preceded by the data which was signed at the third-to-last element on the stack.

`exit`	use A as success value; end
`exp`	A raised to the Bth power. Fail if A == B == 0 and on overflow
`expw`	A raised to the Bth power as a 128-bit result in two uint64s. X is the high 64 bits, Y is the low. Fail if A == B == 0 or if the results exceeds 2^128-1
`extract`	A range of bytes from A starting at B up to but not including B+C. If B+C is larger than the array length, the program fails `extract3` can be called using `extract` with no immediates.
`extract_uint16`	A uint16 formed from a range of big-endian bytes from A starting at B up to but not including B+2. If B+2 is larger than the array length, the program fails
`extract_uint32`	A uint32 formed from a range of big-endian bytes from A starting at B up to but not including B+4. If B+4 is larger than the array length, the program fails

`min_balance`	minimum required balance for account A, in microalgos. Required balance is affected by ASA, App, and Box usage. When creating or opting into an app, the minimum balance grows before the app code runs, therefore the increase is visible there. When deleting or closing out, the minimum balance decreases after the app executes. Changes caused by inner transactions or box usage are observable immediately following the opcode effecting the change. params: Txn.Accounts offset (or, since v4, an available account address), available application id (or, since v4, a Txn.ForeignApps offset). Return: value.
`mulw`	A times B as a 128-bit result in two uint64s. X is the high 64 bits, Y is the low

`select_uint64`	selects one of two values based on top-of-stack: B if C != 0, else A
`setbit_bytes`	Copy of (byte-array or integer) A, with the Bth bit set to (0 or 1) C. If B is greater than or equal to the bit length of the value (8*byte length), the program fails When A is a uint64, index 0 is the least significant bit. Setting bit 3 to 1 on the integer 0 yields 8, or 2^3. When A is a byte array, index 0 is the leftmost bit of the leftmost byte. Setting bits 0 through 11 to 1 in a 4-byte-array of 0s yields the byte array 0xfff00000. Setting bit 3 to 1 on the 1-byte-array 0x00 yields the byte array 0x10.
`setbit_uint64`	Copy of (byte-array or integer) A, with the Bth bit set to (0 or 1) C. If B is greater than or equal to the bit length of the value (8*byte length), the program fails When A is a uint64, index 0 is the least significant bit. Setting bit 3 to 1 on the integer 0 yields 8, or 2^3. When A is a byte array, index 0 is the leftmost bit of the leftmost byte. Setting bits 0 through 11 to 1 in a 4-byte-array of 0s yields the byte array 0xfff00000. Setting bit 3 to 1 on the 1-byte-array 0x00 yields the byte array 0x10.
`setbyte`	Copy of A with the Bth byte set to small integer (between 0..255) C. If B is greater than or equal to the array length, the program fails
`sha256`	SHA256 hash of value A, yields [32]byte

Partition the string into three parts using the given separator.

This will search for the separator in the string. If the separator is found, returns a 3-tuple containing the part before the separator, the separator itself, and the part after it.

If the separator is not found, returns a 3-tuple containing the original string and two empty strings.

removeprefix()¶

Return a str with the given prefix string removed if present.

If the string starts with the prefix string, return string[len(prefix):]. Otherwise, return a copy of the original string.

removesuffix()¶

Return a str with the given suffix string removed if present.

If the string ends with the suffix string and that suffix is not empty, return string[:-len(suffix)]. Otherwise, return a copy of the original string.

replace()¶

Return a copy with all occurrences of substring old replaced by new.

count Maximum number of occurrences to replace. -1 (the default value) means replace all occurrences.

If the optional argument count is given, only the first count occurrences are replaced.

rfind()¶

S.rfind(sub[, start[, end]]) -> int

Return the highest index in S where substring sub is found, such that sub is contained within S[start:end]. Optional arguments start and end are interpreted as in slice notation.

Return -1 on failure.

rindex()¶

S.rindex(sub[, start[, end]]) -> int

Return the highest index in S where substring sub is found, such that sub is contained within S[start:end]. Optional arguments start and end are interpreted as in slice notation.

Raises ValueError when the substring is not found.

rjust()¶

Return a right-justified string of length width.

Padding is done using the specified fill character (default is a space).

rpartition()¶

Partition the string into three parts using the given separator.

If the separator is not found, returns a 3-tuple containing two empty strings and the original string.

rsplit()¶

Return a list of the substrings in the string, using sep as the separator string.

sep The separator used to split the string.

When set to None (the default value), will split on any whitespace
character (including \n \r \t \f and spaces) and will discard
empty strings from the result.

maxsplit Maximum number of splits. -1 (the default value) means no limit.

Splitting starts at the end of the string and works to the front.

rstrip()¶

Return a copy of the string with trailing whitespace removed.

If chars is given and not None, remove characters in chars instead.

split()¶

Return a list of the substrings in the string, using sep as the separator string.

sep The separator used to split the string.

When set to None (the default value), will split on any whitespace
character (including \n \r \t \f and spaces) and will discard
empty strings from the result.

maxsplit Maximum number of splits. -1 (the default value) means no limit.

Splitting starts at the front of the string and works to the end.

Note, str.split() is mainly useful for data that has been intentionally delimited. With natural text that includes punctuation, consider using the regular expression module.

splitlines()¶

Return a list of the lines in the string, breaking at line boundaries.

Line breaks are not included in the resulting list unless keepends is given and true.

startswith()¶

S.startswith(prefix[, start[, end]]) -> bool

strip()¶

Return a copy of the string with leading and trailing whitespace removed.

If chars is given and not None, remove characters in chars instead.

title()¶

Return a version of the string where each word is titlecased.

More specifically, words start with uppercased characters and all remaining cased characters have lower case.

translate()¶

Replace each character in the string using the given translation table.

table Translation table, which must be a mapping of Unicode ordinals to Unicode ordinals, strings, or None.

upper()¶: Return a copy of the string converted to uppercase.

zfill()¶

Pad a numeric string with zeros on the left, to fill a field of the given width.

The string is never truncated.

class algopy.op.EllipticCurve¶

Elliptic Curve functions Native TEAL ops: ec_add, ec_map_to, ec_multi_scalar_mul, ec_pairing_check, ec_scalar_mul, ec_subgroup_check

static add( g: algopy.op.EC, a: algopy.Bytes | bytes, b: algopy.Bytes | bytes, /, ) → algopy.Bytes¶

for curve points A and B, return the curve point A + B A and B are curve points in affine representation: field element X concatenated with field element Y. Field element Z is encoded as follows. For the base field elements (Fp), Z is encoded as a big-endian number and must be lower than the field modulus. For the quadratic field extension (Fp2), Z is encoded as the concatenation of the individual encoding of the coefficients. For an Fp2 element of the form Z = Z0 + Z1 i, where i is a formal quadratic non-residue, the encoding of Z is the concatenation of the encoding of Z0 and Z1 in this order. (Z0 and Z1 must be less than the field modulus).

The point at infinity is encoded as (X,Y) = (0,0). Groups G1 and G2 are denoted additively.

Fails if A or B is not in G. A and/or B are allowed to be the point at infinity. Does not check if A and B are in the main prime-order subgroup.

Parameters:: g (EC) – curve index

Native TEAL opcode: ec_add

static map_to(g: algopy.op.EC, a: algopy.Bytes | bytes, /) → algopy.Bytes¶

maps field element A to group G BN254 points are mapped by the SVDW map. BLS12-381 points are mapped by the SSWU map. G1 element inputs are base field elements and G2 element inputs are quadratic field elements, with nearly the same encoding rules (for field elements) as defined in ec_add. There is one difference of encoding rule: G1 element inputs do not need to be 0-padded if they fit in less than 32 bytes for BN254 and less than 48 bytes for BLS12-381. (As usual, the empty byte array represents 0.) G2 elements inputs need to be always have the required size.

Parameters:: g (EC) – curve index

Native TEAL opcode: ec_map_to

static pairing_check( g: algopy.op.EC, a: algopy.Bytes | bytes, b: algopy.Bytes | bytes, /, ) → bool¶

1 if the product of the pairing of each point in A with its respective point in B is equal to the identity element of the target group Gt, else 0 A and B are concatenated points, encoded and checked as described in ec_add. A contains points of the group G, B contains points of the associated group (G2 if G is G1, and vice versa). Fails if A and B have a different number of points, or if any point is not in its described group or outside the main prime-order subgroup - a stronger condition than other opcodes. AVM values are limited to 4096 bytes, so ec_pairing_check is limited by the size of the points in the groups being operated upon.

Parameters:: g (EC) – curve index

Native TEAL opcode: ec_pairing_check

static scalar_mul( g: algopy.op.EC, a: algopy.Bytes | bytes, b: algopy.Bytes | bytes, /, ) → algopy.Bytes¶

for curve point A and scalar B, return the curve point BA, the point A multiplied by the scalar B. A is a curve point encoded and checked as described in ec_add. Scalar B is interpreted as a big-endian unsigned integer. Fails if B exceeds 32 bytes.

Parameters:: g (EC) – curve index

Native TEAL opcode: ec_scalar_mul

static scalar_mul_multi( g: algopy.op.EC, a: algopy.Bytes | bytes, b: algopy.Bytes | bytes, /, ) → algopy.Bytes¶

for curve points A and scalars B, return curve point B0A0 + B1A1 + B2A2 + … + BnAn A is a list of concatenated points, encoded and checked as described in ec_add. B is a list of concatenated scalars which, unlike ec_scalar_mul, must all be exactly 32 bytes long. The name ec_multi_scalar_mul was chosen to reflect common usage, but a more consistent name would be ec_multi_scalar_mul. AVM values are limited to 4096 bytes, so ec_multi_scalar_mul is limited by the size of the points in the group being operated upon.

Parameters:: g (EC) – curve index

Native TEAL opcode: ec_multi_scalar_mul

static subgroup_check(g: algopy.op.EC, a: algopy.Bytes | bytes, /) → bool¶

1 if A is in the main prime-order subgroup of G (including the point at infinity) else 0. Program fails if A is not in G at all.

In almost all cases, smart contracts should directly handle non-encoded byte-strings. This opcode should only be used in cases where base64 is the only available option, e.g. interoperability with a third-party that only signs base64 strings.

Decodes A using the base64 encoding E. Specify the encoding with an immediate arg either as URL and Filename Safe (URLEncoding) or Standard (StdEncoding). See RFC 4648 sections 4 and 5. It is assumed that the encoding ends with the exact number of = padding characters as required by the RFC. When padding occurs, any unused pad bits in the encoding must be set to zero or the decoding will fail. The special cases of \n and \r are allowed but completely ignored. An error will result when attempting to decode a string with a character that is not in the encoding alphabet or not one of =, \r, or \n.

algopy.op.min_balance(a: algopy.Account | algopy.UInt64 | int, /) → algopy.UInt64¶

minimum required balance for account A, in microalgos. Required balance is affected by ASA, App, and Box usage. When creating or opting into an app, the minimum balance grows before the app code runs, therefore the increase is visible there. When deleting or closing out, the minimum balance decreases after the app executes. Changes caused by inner transactions or box usage are observable immediately following the opcode effecting the change. params: Txn.Accounts offset (or, since v4, an available account address), available application id (or, since v4, a Txn.ForeignApps offset). Return: value.

Copy of (byte-array or integer) A, with the Bth bit set to (0 or 1) C. If B is greater than or equal to the bit length of the value (8*byte length), the program fails When A is a uint64, index 0 is the least significant bit. Setting bit 3 to 1 on the integer 0 yields 8, or 2^3. When A is a byte array, index 0 is the leftmost bit of the leftmost byte. Setting bits 0 through 11 to 1 in a 4-byte-array of 0s yields the byte array 0xfff00000. Setting bit 3 to 1 on the 1-byte-array 0x00 yields the byte array 0x10.
