Solana

In Anchor you need to build a verifiable build using Docker to produce a consistent executable.

IDL (Interface Definition Language) is Solana's lingo for ABI. An IDL is uploaded to an account on-chain and block explorers are able to pick it up automatically.

anchor idl init --filepath target/idl/your_program.json $PROGRAM_ID --provider.cluster mainnet

To verify that it is stored correctly, run

anchor idl fetch $PROGRAM_ID --provider.cluster mainnet

Solana programs are upgradeable by default, so you can also upgrade the IDL:

anchor idl upgrade --filepath target/idl/your_program.json $PROGRAM_ID --provider.cluster mainnet
