@liens/cli

The command-line half of the same toolkit the LIEN Designer runs in the browser. Both call @liens/sdk; both fold a Composition through the same Rust hook-runtime the Anchor executor links. The number lien prints is the number the chain runs.

npm i -g @liens/cli
lien list                                              # the six standard knots
lien create slip-knot --pool SOL-USDC --venue marginfi # scaffold a Composition
lien simulate --pool SOL-USDC --steps 240              # backtest against pool history
lien deploy --cluster devnet                           # print the on-chain install plan (does NOT broadcast)

The actual broadcast is lien deploy --cluster <cluster> --execute --keypair <path>. The --execute flag is explicit by design — a fat-fingered lien deploy should not write to mainnet.

Six commands

| command | what it does | |---|---| | lien list | print the six standard knots with their flags, lifecycle events, params | | lien create <knot> --pool <pair> --venue <lender> | scaffold a lien.toml with the named knot installed | | lien simulate --pool <pair> --steps <n> | run the Composition against <n> steps of pool history; print accept / reject / side-effects | | lien deploy --cluster <cluster> | print the install plan; --execute --keypair <path> to broadcast | | lien action --workflow <name> | write a GitHub Actions workflow that runs lien simulate on every push | | lien publish <knot> | (coming) wrap publish_hook for knot authors |

Six standard knots

| knot | code id | fires on | |---|---|---| | the slip knot | DynamicLTV | beforeBorrow / afterDeposit | | the timer hitch | TimeTriggerLiq | beforeLiquidate | | the lock knot | WhitelistBorrow | beforeBorrow | | the double bowline | AntiMEVLiq | beforeLiquidate | | the double helix | AutoHedge | afterBorrow / afterDeposit | | the rolling hitch | ReputationRate | beforeBorrow |

Each is a real implementation with passing tests on the Rust side. The CLI prints them out so you don't have to open the browser.

Lender targets

Marginfi v2 · Kamino Lend · Save (formerly Solend). Adapters ship from source for the moment — pnpm -r build from the monorepo covers them — npm publish for adapter packages tracks the next stable release.
