文档

Tempo Stable + Uniswap Swaps

Use this skill for low-friction Tempo execution with Foundry (cast) and Uniswap Trade API.

One-File Mode (Clawhub-Friendly)

Use this SKILL.md alone. No other files are required.

If scripts are unavailable, run the command playbooks in this file directly.

Network + Tokens

  • Chain: Tempo mainnet (chainId=4217)
  • RPC: https://rpc.presto.tempo.xyz
  • pathUSD: 0x20C0000000000000000000000000000000000000
  • USDC.e: 0x20c000000000000000000000b9537d11c60e8b50
  • TDOGE: 0x20C000000000000000000000d5d5815Ae71124d1
  • Permit2: 0x000000000022D473030F116dDEE9F6B43aC78BA3

Foundry Prereq Check (Required)

Check:

bash
command -v cast && cast --version

Install if missing:

bash
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

bash
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

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

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

bash
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
  1. Build swap tx from quote object (POST /v1/swap with { "quote": <quote_object> }), then simulate:
bash
curl -s "${RPC_URL:-https://rpc.presto.tempo.xyz}" -H 'content-type: application/json' --data \
'{"jsonrpc":"2.0","id":1,"method":"eth_call","params":[{"from":"<WALLET>","to":"<SWAP_TO>","data":"<SWAP_DATA>"},"latest"]}'
  1. Broadcast:
bash
cast send <SWAP_TO> "<SWAP_DATA>" \
  --private-key "$PRIVATE_KEY" \
  --rpc-url "${RPC_URL:-https://rpc.presto.tempo.xyz}" \
  --gas-limit <GAS_LIMIT> --gas-price <MAX_FEE_PER_GAS>

Known Errors

  • AllowanceExpired(...): set Permit2 allowance for token+spender.
  • InsufficientAllowance: approve token to Permit2.
  • Quote exists but swap reverts: refresh quote and retry.
  • Full pathUSD transfer fails: leave fee headroom.

Optional Script

If available, use:

bash
scripts/uniswap_exact_input_swap.sh --token-in <TOKEN_IN> --token-out <TOKEN_OUT> --amount-in <RAW_AMOUNT>
