Programs

Please note that all "Testnet" Programs are deployed to Solana Mainnet. This is to allow for proper liquidity on all functionality.

Claimable Tokens

This program powers the Audius reward system, and allows Solana non-custodial token accounts to be created for Audius users that are represented by an Ethereum wallet. This program is also referred to as the "User Bank".

This program was developed originally to allow for a very specific use case: make it so users who only have ethereum accounts can receive solana token rewards. Leveraging the solana secp instructions, we derive token accounts belonging to a PDA on the claimable tokens program whose ability to transfer from is controlled by ethereum signatures. This allows for us to send rewards to a user and for them to be later claimed without needing them to even have an active session to create a receiving wallet.

Payment Router

This program is responsible for distributing any SPL Token across different provided Solana associated token accounts, with amounts determined by a given percent split.

It is intended to be used with SPL-AUDIO and SPL-USDC. While payments can be made independently of the Payment Router program, it is designed to improve space-efficiency and usability off-chain.

Reward Manager

This program allows for Audius users to claim rewards given attestations from Node Operators that they have successfully completed a challenge.

For example, to claim the “I've completed my profile reward,” a user may ask for a set of Discovery Node Operators to provide a cryptographic proof that they have completed the challenge and submit that to chain. If the signatures are valid, tokens are dispensed

Staking Bridge

This program has 2 main functions:

1. Swap SPL-USDC tokens to SPL-AUDIO tokens via the Raydium AMM Program.
2. Convert SPL-AUDIO tokens to ERC20-AUDIO tokens via the Wormhole Token Bridge.

The methods in this program are intentionally permissionless, allowing any user willing to pay transaction fees to interact.

The methods of the Staking Bridge are independent to reduce price impact of swaps and fees associated with bridging tokens.
