Agents

Build on Arc or Robinhood. Read launches through the public JSON API and prepare contract calls from your own wallet. Check each network's deployment availability below.

Call launch(params) on the selected network's factory. First call findSalt(...) with the final token parameters so the token address sorts above the quote address. The example below uses Arc and USDC.

Launch function signatureABI reference
launch((string,string,string,address,uint256,int24,uint24,bytes32,(address,uint16)[]))

Example only. Set your wallet address and a bytes32 base salt, then use the returned salt with identical token parameters. Recompute it if metadataURI changes. Never share your private key.

Parameters, without the guesswork

quote
On Arc, use the USDC ERC-20 interface at 0x3600000000000000000000000000000000000000 with 6 decimals. Arc gas uses the same USDC balance at 18 decimals; its factory rejects address-zero native quotes. On Robinhood, the default quote is USDG at 0x5fc5360D0400a0Fd4f2af552ADD042D716F1d168, also 6 decimals. Robinhood gas is a separate ETH balance.
supply
0 means the default 1B supply.
startTick
Sets the opening market cap. A multiple of 200; calculate it using the actual quote's decimals (6 for USDC or USDG), then review the resulting market cap.
lpFee
In pips: 0, 10000 = 1%, or 30000 = 3%.
recipients
Empty means fees are burned. Otherwise, shares are in bps and sum to 10000.

Add metadata first

Optional

For an image, description or links, choose a random bytes32 meta_key once. Build metadataURI as https://fazenpad.com/api/launch/meta/<lowercase-launcher>/<lowercase-meta_key>, then run findSalt(...) with that URI. Register metadata with the returned salt and the unchanged key. The response contains uri and the predicted token address; verify both before launch.

A first buy is optional and is a separate transaction after launch. Keep enough USDC for gas as well as the buy on Arc; on Robinhood, keep ETH for gas alongside the quote asset. Set chain to arc or robinhood to match the network used for salt prediction and launch.

Raw token and quote amounts are decimal integer strings. Use quote_decimals for quote amounts, not a blanket 18 decimals. price_quote and fdv_quote are numbers in the token's quote asset; explicit price_usd, fdv_usd and volume_usd fields are USD values and may be null when pricing is unavailable.

Poll modestly and back off on errors. Indexing and server-side caching mean responses are not a guarantee of the latest chain state, even when an HTTP response uses no-store.

03

Trade & collect

Standard pools. Direct contract calls.

Swap

Speak Uniswap v4

Pools use tick spacing 200 and no hook. Get the actual pool key with poolKeyOf(token) on the matching network's factory. Swap through its Universal Router with a V4_SWAP command, using the pool's quote asset and decimals.

Collect

Pay out accrued fees

Anyone may call collect(tokenId) on the matching network's locker to pay out accrued fees to its registered recipients. Use that network's address from the contract list above.

Use Arc Foundry for local Arc execution tests. A standard EVM fork does not reproduce Arc's native USDC behavior.

POST

Sync your transaction

After a transaction you sent, request immediate indexing with this endpoint. Background polling normally runs about every 15s; receipt availability and RPC errors can delay indexing.
