Mainnet.
lien_hook_executor is live on Solana mainnet at 5yNMqcyZsGQJk4xvw4jjvoRBSnGs8mgramEa3HQe5faD. same Program ID as the devnet binary, byte-identical .so, byte-identical decision fold.

@Liens_fi well, gg its prob @Patcha_fi dev for real and that 5% wallet is notorious for holding coins hostage like this. He's also down 250k all time and never makes money so great top holder to have for sure.

mainnet broadcast in ~5 minutes.
lien_hook_executor going live on Solana mainnet under the same Program ID as the devnet binary — 5yNMqcyZsGQJk4xvw4jjvoRBSnGs8mgramEa3HQe5faD. same .so, same byte-identical decision fold, no surprise instructions.
payer + program keypair + balance gates all checked off. the next reply on this thread is the mainnet tx and the Explorer link without ?cluster=devnet. dexscreener boost goes up alongside so the page traffic peaks while the tx is settling.

The executor.
lien_hook_executor is on Solana devnet at 5yNMqcyZsGQJk4xvw4jjvoRBSnGs8mgramEa3HQe5faD (Anchor 0.31.1). Mainnet deploy is staged for the next push - same Program ID will be reused, same .so, same byte-identical decision fold shared with the off-chain hook-runtime. The decision you backtested in the Designer is the decision the chain will run, on devnet today and on mainnet shortly.
loader: BPFLoaderUpgradeab1e11111111111111111111111
mainnet deploy: the keypair, the cluster, and the balance gates have all been checked off; the broadcast is the last step. When it lands, this thread updates with the mainnet tx and the Explorer link drops `?cluster=devnet`.
what runs on devnet today: register_pool / install_composition / update_composition / run_composition / publish_hook. the six standard knots. Marginfi / Kamino / Save adapters CPI into run_composition from a sample harness.

Six standard knots. One library.
the slip knot (DynamicLTV in code) — beforeBorrow / afterDeposit, rope red
the timer hitch (TimeTriggerLiq) — beforeLiquidate, rope cyan
the lock knot (WhitelistBorrow) — beforeBorrow, rope purple
the double bowline (AntiMEVLiq) — beforeLiquidate, rope green
the double helix (AutoHedge) — afterBorrow / afterDeposit, rope yellow
the rolling hitch (ReputationRate) — beforeBorrow, rope ivory
Each is a real implementation with passing tests. Read every one.

@0xblackchip @forgottendazai @Oguzhansumer09 on me — got tunnel vision pushing the @liens import fix and ran the squash sync instead of the incremental one. mirror briefly looked like a single commit at HEAD. restored now

Tie knots like rigging a ship.
liens.fi/designer is open. Drag the slip knot, the timer hitch, the double bowline and three more onto an eight-slot Composition, set priority, and backtest against Marginfi / Kamino / Save event history — before anything touches the chain. The Designer calls the same Rust runtime the executor ships.
Composing and backtesting are free.

No lender fork. A knot attaches alongside a Marginfi, Kamino, or Save pool through an Anchor 0.31 executor, scoped by PDAs — the lender stays one audited contract.
And the decision you backtest is the decision the chain runs: the off-chain Rust hook-runtime and the on-chain executor fold the knot stack from a byte-identical function. No drift between simulation and execution.
English
A knot is a hook for a loan lifecycle. The lifecycle has eight events — before/after deposit, borrow, repay, liquidate. The trigger is one of those eight callbacks; the decision returns accept (optionally with a side effect — override LTV, delay liquidation, route a CPI) or reject.
Six ship as a standard library, each tested: the slip knot, the timer hitch, the lock knot, the double bowline, the double helix, the rolling hitch.

Why hooks for Solana lending.
If you borrow on a Solana lender, your position runs on one liquidation curve in every condition — the same threshold for an idle weekend and a 30% nuke, the same liquidation auction whether the searcher is a friend or a bot. On EVM, Uniswap v4 (Uniswap Labs 2024) fixed pool-level callbacks with hooks. Solana's lenders never had a hook layer. LIEN is it.
