Deploy a lending program (optional)

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.

Create a lending market

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.

Usage

solarti-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 solarti-token-lending create-market --help for more details and options.

Example

solarti-token-lending \
  --program      6TvznH3B2e3p2mbhufNBpgSrLx6UkgvxtVQvopEZ2kuH \
  --fee-payer    owner.json \
