# Solignition Docs

> Documentation for Solignition — a permissionless, non-custodial DeFi lending protocol on Solana that funds on-chain program deployments. Builders borrow SOL to deploy and repay to reclaim upgrade authority; liquidity providers deposit SOL and earn yield from borrower interest.

These docs are served as a client-rendered single-page app. The raw Markdown (MDX) source for every page below is available on GitHub at https://github.com/Peacanduck/solignition/tree/main/docs/src/content and is the most reliable source for automated readers.

## Get started
- [Introduction](https://docs.solignition.xyz/get-started/intro): What Solignition is and why it exists.
- [Quickstart](https://docs.solignition.xyz/get-started/quickstart): From zero to a deployed program in five minutes on devnet.
- [Install the CLI](https://docs.solignition.xyz/get-started/cli-install): Pick a distribution channel and verify it works.

## For builders
- [Borrow & deploy](https://docs.solignition.xyz/builders/borrow-flow): End-to-end mental model of what happens when you run solignition deploy.
- [Upgrade authority](https://docs.solignition.xyz/builders/authority): The escrow model — who can do what to your program while the loan is live.
- [Repaying loans](https://docs.solignition.xyz/builders/repay): Pay principal + accrued interest, get your upgrade authority back.
- [What if I default?](https://docs.solignition.xyz/builders/default): On expiry the deployed program is closed and reclaimed SOL returns to the vault.

## For LPs
- [Deposit SOL](https://docs.solignition.xyz/lps/deposit): Move SOL into the vault and start earning yield from borrower interest.
- [Shares & yield](https://docs.solignition.xyz/lps/shares): How LP shares accrue value from borrower interest and reclaimed defaults.
- [Withdrawing](https://docs.solignition.xyz/lps/withdraw): Redeem some or all of your shares back to SOL.

## Protocol
- [How it works](https://docs.solignition.xyz/protocol/mechanics): Config singleton + per-LP records + per-loan records + an off-chain deployer.
- [Interest math](https://docs.solignition.xyz/protocol/interest): Linear, time-prorated interest. No compounding. Paid on repay.
- [Loan lifecycle](https://docs.solignition.xyz/protocol/lifecycle): State machine for the Loan account — six states, four actors, one happy path.
- [Fees & treasury](https://docs.solignition.xyz/protocol/fees): Where every lamport goes — admin fees, interest splits, treasury controls.
