Build

The token swap program contains hard-coded constraints on fees and fee account owners. For this build, available at program id SwaPpA9LAaLfeLi3a68M4DjnLqgtticKg6CnyNwgAC8 on devnet, testnet, and mainnet-beta, the fee account for any pool must be owned by HfoTxFR1Tm6kGmWgYWD6J7YHVy1UwqSULUGVLXkJqaKN.

Run the build command from token-swap/program:

SWAP_PROGRAM_OWNER_FEE_ADDRESS=HfoTxFR1Tm6kGmWgYWD6J7YHVy1UwqSULUGVLXkJqaKN cargo build-bpf --features=production

SPL Memo v3.0.0

In addition to validating a string of UTF-8 encoded characters, the Memo program now:

• verifies that any accounts provided are signers of the transaction
• logs the memo, as well as any verified signer addresses, to the transaction log, so that anyone can easily observe memos and know they were approved by zero or more addresses by inspecting the transaction log from a trusted provider.
