It is located in ./crates/defi-entities/private.rs and looks like
pub const KEY_ENCRYPTION_PWD: [u8; 16] = [35, 48, 129, 101, 133, 220, 104, 197, 183, 159, 203, 89, 168, 201, 91, 130];To change key encryption password run and replace content of KEY_ENCRYPTION_PWD
cargo run --bin keys generate-password To get encrypted key run:
cargo run --bin keys encrypt --key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80DATA=<ENCRYPTED_PRIVATE_KEY> cargo run --bin loomMakefile is shipped with following important commands:
- build - builds all binaries
- fmt - formats loom with rustfmt
- pre-release - check code with rustfmt and clippy
- clippy - check code with clippy
Testing Loom requires two environment variables pointing at archive node:
- MAINNET_WS - websocket url of archive node
- MAINNET_HTTP - http url of archive node
To run tests:
make test- Paradigm - Paradigm. All those inspiring products : RETH / REVM / Alloy / Ethers
- darkforestry - AMM Crate
- 0xKitsune - Uniswap Math crate
- Onbjerg - Flashbots crate
