Foundry Prereq Check (Required)

command -v cast && cast --version

Install if missing:

curl -L https://foundry.paradigm.xyz | bash
foundryup

pathUSD vs USDC.e

  • pathUSD is Tempo-native infrastructure stablecoin used in routing/fees.
  • USDC.e is bridged stablecoin liquidity.
  • Do not attempt exact full-balance pathUSD transfers; leave fee headroom.

Required Tools + Env

  • Tools: cast, curl, jq
  • Env:
    • PRIVATE_KEY
    • UNISWAP_API_KEY
    • Optional: RPC_URL (default above)

Quick Balance Checks

WALLET=$(cast wallet address --private-key "$PRIVATE_KEY")
cast call 0x20C0000000000000000000000000000000000000 \
  "balanceOf(address)(uint256)" "$WALLET" --rpc-url "${RPC_URL:-https://rpc.presto.tempo.xyz}"
cast call 0x20c000000000000000000000b9537d11c60e8b50 \
  "balanceOf(address)(uint256)" "$WALLET" --rpc-url "${RPC_URL:-https://rpc.presto.tempo.xyz}"

Transfer pathUSD

cast send 0x20C0000000000000000000000000000000000000 \
  "transfer(address,uint256)" <TO> <AMOUNT_RAW> \
  --private-key "$PRIVATE_KEY" --rpc-url "${RPC_URL:-https://rpc.presto.tempo.xyz}" --gas-limit 100000

Swap Any Token on Tempo via Uniswap (Exact Input)

  1. Quote:
curl -sS https://trade-api.gateway.uniswap.org/v1/quote \
  -H 'content-type: application/json' \
  -H "x-api-key: $UNISWAP_API_KEY" \
  --data '{
    "type":"EXACT_INPUT",
    "amount":"<AMOUNT_IN_RAW>",
    "tokenInChainId":4217,
    "tokenOutChainId":4217,
    "tokenIn":"<TOKEN_IN>",
    "tokenOut":"<TOKEN_OUT>",
    "swapper":"<WALLET>",
    "slippageTolerance":2.5
  }'
  1. Ensure approvals: TOKEN_IN -> Permit2:
cast send <TOKEN_IN> "approve(address,uint256)" \
  0x000000000022D473030F116dDEE9F6B43aC78BA3 \
  0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff \
  --private-key "$PRIVATE_KEY" --rpc-url "${RPC_URL:-https://rpc.presto.tempo.xyz}" --gas-limit 900000

Permit2 -> spender (spender from quote permitData.values.spender):

EXP=$(( $(date +%s) + 31536000 ))
cast send 0x000000000022D473030F116dDEE9F6B43aC78BA3 \
  "approve(address,address,uint160,uint48)" \
  <TOKEN_IN> <SPENDER> 1461501637330902918203684832716283019655932542975 "$EXP" \
  --private-key "$PRIVATE_KEY" --rpc-url "${RPC_URL:-https://rpc.presto.tempo.xyz}" --gas-limit 900000

x-research

General-purpose X/Twitter research agent. Searches X for real-time perspectives, dev discussions, product feedback, cultural takes, breaking news, and expert opinions. Works like a web research agent but uses X as the source. Use when: (1) user says "x research", "search x for", "search twitter for", "what are people saying about", "what's twitter saying", "check x for", "x search", "/x-research", (2) user is working on something where recent X discourse would provide useful context (new library releases, API changes, product launches, cultural events, industry drama), (3) user wants to find what devs/experts/community thinks about a topic. NOT for: posting tweets, account management, or historical archive searches beyond 7 days.
