# Agent Credit Protocol > AGC is Solana-native credit inventory for machine economies. It expands circulating AGC only when reserves, collateral, liquidity, oracle quality, credit demand, and hard mint caps prove the balance sheet can carry more supply. Important notes: - AGC is not a hard-peg stablecoin. - xAGC is the long-duration expansion share. - USDC and USDT are defensive cash reserves. - BTC wrappers are strategic reserve collateral with haircuts. - Tokenized stocks and RWAs start isolated before they count in global reserve coverage. - Credit facilities mint AGC against approved collateral, underwriter reserve, debt caps, and Pyth-backed oracle health. - Buyback defense uses campaign escrows that release USDC only after AGC is delivered and burned. - Launch collateral presets cover USDC, USDT, one liquid BTC wrapper, and isolated RWAs. - The Raydium-first buyback adapter is an execution client around the onchain campaign invariant. - Local-validator integration tests cover SPL mint/vault initialization and freeze-authority rejection. - Optional Solana swap adapters are telemetry, not complete global demand, because users can trade public pools through wallets and aggregators. ## Human Docs - [Protocol docs](/docs): Human-readable docs page hosted in the frontend. - [Solana credit machine](/docs/solana-credit-machine.md): Markdown source for the updated AGC Solana design. - [Risk presets](/docs/risk-parameter-presets.md): Launch collateral and policy presets. - [User examples](/docs/user-examples.md): Holder, underwriter, borrower, defense, and liquidation examples. - [Upgrade runbook](/docs/upgrade-migration-runbook.md): Upgrade and migration operating process. - [Raydium adapter](/docs/raydium-buyback-adapter.md): Buyback campaign execution adapter model. ## AI Docs - [Full AI context](/llms-full.txt): Single-file summary of the protocol thesis, reserve model, policy model, credit facilities, governance, demand path, and implementation status. ## Source Files - [Solana program](https://github.com/c0rv0s/ACP/tree/master/solana/programs/agc_solana/src/lib.rs): Anchor program containing the Solana policy, vault, collateral registry, and credit facility implementation. - [Root README](https://github.com/c0rv0s/ACP/blob/master/README.md): Repository overview. - [Solana README](https://github.com/c0rv0s/ACP/blob/master/solana/README.md): Solana build and account notes. ## Optional - [Landing page](/): Public product framing. - [AGC console](/dashboard): AGC swap, xAGC, credit facility, and expansion-state surface.
