BaseYield — Smart Contracts

Non-custodial LP automation on Base L2. Users configure safeguard conditions on-chain. Gelato executes rebalances when conditions are met. Developer earns 7.5% of collected trading fees.

Architecture

BaseYieldManager.sol
│
├── setConditions(tokenId, conditions)   — user stores safeguards on-chain
├── activate(tokenId)                    — enables automation for a position
├── pause(tokenId)                       — emergency stop (user only, instant)
├── resume(tokenId)                      — resume after pause
├── deactivate(tokenId)                  — graceful stop
│
├── checkUpkeep(tokenId, owner)          — Gelato resolver (view, gas-free)
└── rebalance(tokenId, owner)            — Gelato execution (onlyGelato)

Key properties:

• Non-custodial — contract never holds user funds except atomically during rebalance
• Non-upgradeable — no proxy, no admin, immutable after deployment
• User-governed — all conditions set by user, enforced by contract
• 7.5% fee on collected trading fees only — never on principal

Deployment

Base Sepolia (testnet)

# Verify your .env has BASE\_SEPOLIA\_RPC, DEPLOYER\_PRIVATE\_KEY,
# SLIPSTREAM\_NPM\_ADDRESS, GELATO\_AUTOMATE\_ADDRESS, FEE\_RECIPIENT\_ADDRESS

  --rpc-url base\_sepolia \\
  --broadcast \\
  --verify \\
  -vvvv

Base Mainnet

# ⚠️  Do NOT deploy to mainnet without a completed professional audit
# ⚠️  Use a hardware wallet via cast wallet for mainnet deployments

forge script script/Deploy.s.sol \\
  --rpc-url base\_mainnet \\
  --broadcast \\
  --verify \\
  --ledger \\
