Jito MEV Tip Distribution NCN

Testing Setup

Prerequisites

1. Set up test-ledger: ./tip-router-operator-cli/scripts/setup-test-ledger.sh

   • NOTE: This script fails on the edge version of Solana. Currently it's being ran with 1.18.26. sh -c "$(curl -sSfL https://release.anza.xyz/v1.18.26/install)"

2. Build the tip router program: cargo build-sbf --manifest-path program/Cargo.toml --sbf-out-dir integration_tests/tests/fixtures

   • NOTE: Given the current state of Cargo.lock, you must use a version of cargo-build-sbf that has a rust toolchain higher than 1.74.0. For now, switch to the edge version to build this. sh -c "$(curl -sSfL https://release.anza.xyz/v2.2.0/install)". Another option would be to manually set the Cargo.lock file version to 3 instead of 4 (coral-xyz/anchor#3392 (comment))

3. Run tests: SBF_OUT_DIR=integration_tests/tests/fixtures cargo test

   • NOTE: If you are still on the edge version of Solana CLI probably best to switch back to 1.18.26

Deploy and Upgrade

• build .so file: cargo-build-sbf

• create a new keypair: solana-keygen new -o target/tmp/buffer.json

• Deploy: solana program deploy --use-rpc --buffer target/tmp/buffer.json --with-compute-unit-price 10000 --max-sign-attempts 10000 target/deploy/jito_tip_router_program.so

• (Pre Upgrade) Write to buffer: solana program write-buffer --use-rpc --buffer target/tmp/buffer.json --with-compute-unit-price 10000 --max-sign-attempts 10000 target/deploy/jito_tip_router_program.so

• Upgrade: solana program upgrade $(solana address --keypair target/tmp/buffer.json) $(solana address --keypair target/deploy/jito_tip_router_program-keypair.json)

• Close Buffers: solana program close --buffers

• Upgrade Program Size: solana program extend $(solana address --keypair target/deploy/jito_tip_router_program-keypair.json) 100000
