JSPM

js client to interact with the compressed-token program

WIP.

Requirements

reproduced on mac m2:

• node: v20.9.0
• rustup 1.26.0, rustc 1.73.0, cargo 1.73.0
• solana-cli 1.17.5

Producing events for indexing

First, activate the devenv

. ./scripts/devenv.sh

If you're new, run

./scripts/install.sh

Run the monorepo build script ./scripts/build.sh

Go to stateless.js cd js/stateless.js

and run pnpm run test-validator

this starts a solana-test-validator + auto-initialized the env, programs, and accounts Light needs. It should print: "Executing command solana-test-validator... Waiting for fees to stabilize 1..." Keep the validator running.

Now open another terminal, activate the devenv again + move to js/compressed-token.

now run:

pnpm emit-event:create_mint pnpm emit-event:mint_to pnpm emit-event:transfer

You'll be able to index the emitted events (output utxos) according to the event rust struct on localnet. Create mint doesn't create an output utxo, mint_to doesn't use input_utxos. also note that currently we're creating mock inputs for the transfer, meaning you don't need to run mint_to before transfer.

Troubleshooting

If you're having trouble building the project or cli,

• Nuke git clean -xfd (careful)

• re-run install.sh etc

• you may want to manually build the programs (anchor build) or manually build the cli (pnpm run build in ./cli) before running ./cli/test_bin/run test-validator

Other side notes

1. This is unsafe. We don't verify ZKPs yet, nor do we validate tree roots.
2. this is also what allows us to make up input-utxos for emit-event:transfer
3. on-chain runs a sumcheck on the state transition (outputs, inputs).
