Algorand

This page includes details for working with Algorand environment chains.

Developer Tools

The recommended development tool for Algorand is Algokit.

Addresses

Because Wormhole works with many environments, the Wormhole address format is normalized. For Algorand chains, a Wormhole formatted address is the 58-character address decoded from base32 with its checksum removed. E.g. M7UT7JWIVROIDGMQVJZUBQGBNNIIVOYRPC7JWMGQES4KYJIZHVCRZEGFRQ becomes 0x67e93fa6c8ac5c819990aa7340c0c16b508abb1178be9b30d024b8ac25193d45.

Algorand also uses a uint64 for asset and application IDs. These are converted to 32 bytes by first converting to an 8-byte big-endian byte array, then padding with 24 bytes of zeroes. For example, 123 becomes 0x000000000000000000000000000000000000000000000000000000000000007b.

Emitter

The emitter is the application address, normalized to the Wormhole address format.

Consistency Levels

The options for consistencyLevel (i.e., finality) are:

Level Value
Finalized 0

This field may be ignored since the chain provides instant finality.
