A basic command line interface for initializing lending markets and reserves for SPL Token Lending.
See https://spl.solana.com/token-lending for more details
shell
cargo install spl-token-lending-cli
This is optional! You can simply add your own market and reserves to the existing on-chain programs.
If you want to deploy your own program, follow this guide and note the program ID.
A lending market is a collection of reserves that can be configured to borrow and lend with each other.
The lending market owner must sign to add reserves.
shell
spl-token-lending \
--program PUBKEY \
--fee-payer SIGNER \
create-market \
--market-owner PUBKEY
- --program is the lending program ID.
- --fee-payer will sign to pay transaction fees.
- --market-owner is the lending market owner pubkey.
Run spl-token-lending create-market --help for more details and options.
```shell spl-token-lending \ --program 6TvznH3B2e3p2mbhufNBpgSrLx6UkgvxtVQvopEZ2kuH \ --fee-payer owner.json \ create-market \ --market-owner JAgN4SZLNeCo9KTnr8EWt4FzEV1UDgHkcZwkVtWtfp6P
``
Note the lending market pubkey (e.g.7uX9ywsk1X2j6wLoywMDVQLNWAqhDpVqZzL4qm4CuMMT`). You'll use this to add reserves.
A reserve is a liquidity pool that can be deposited into, borrowed from, and optionally used as collateral for borrows.
