Nothing at Priors runs this draft. Its reference contracts go on the testnet only.

Try it

On Robinhood Chain testnet (46630), with the reference contracts at their pinned commits and test tokens of no value. Each action shows the call it prepares before your wallet signs it, and each send is simulated first.

The testnet contracts

Actions

Reads

Deploy your own

Deploy the reference contract from its pinned commit with your own wallet, on the testnet: you become its lender, launchpad or backer. Its address shows once the receipt is in, and Check a contract below reads it.

With an agent

Your agent gets the same lab through the MCP server at https://lab.priors.trade/mcp or the HTTP API described by /openapi.json. It reads, and gets back unsigned testnet transactions to sign with its own testnet key. The lab holds no key of its own for you and never asks for one.

MCP tools for ERC-8462

lab_erc(8462)

What the draft does on the lab, its contracts and an agent's next calls.

lab_setup(address)

Test ETH, test dollars and the testnet identities of an address, with the calls to register one and mint test dollars.

lab_read(8462, "preview_launch", { creator, name, symbol, total_supply })

The token and launch id a creator's next launch will have.

lab_read(8462, "launch_authorization", { creator, name, symbol, total_supply, agent_id, deadline })

The EIP-712 CreatorAuthorization a creator signs to attach its identity to a lab launch.

lab_read(8462, "launch_of", { token })

A lab launch: a visitor's test token (not verified), its creator, launch id, pool, lock, identity.

lab_read(8462, "declarations_of", { token, start, limit, contract })

A token's declarations (what a buyer agent reads first).

lab_read(8462, "declarations_by", { creator, start, limit, contract })

A creator's declarations.

lab_read(8462, "declaration", { declaration_id, contract })

One declaration: creator, identity, allocations, liquidity, fee recipients.

lab_read(8462, "next_venue_declaration", { venue, token, creator, contract })

The id a venue's next declaration of a token will have.

lab_read(8462, "creator_authorization", { declaration_id, venue, token, creator, agent_id, deadline, contract })

The EIP-712 message a creator signs to let a venue attach its identity.

lab_prepare(8462, "launch", { name, symbol, total_supply, creator_allocation, pool_dollars, unlock_at, fee_recipient, agent_id, deadline, creator_signature, financing_loan_id, financing_line })

Launch a test token in one transaction: token, pool, liquidity lock, declaration, fee stream. Who signs: anyone (the creator)

lab_prepare(8462, "approve_financing", { amount })

Let the lab launchpad take a lab loan's principal for the pool. Who signs: the creator

lab_prepare(8462, "declare_venue_creator", { token, creator, agent_id, deadline, creator_signature, contract })

Declare a launch as your own venue. Who signs: the venue (the creator signs unless it is the sender)

lab_prepare(8462, "declare_allocation", { declaration_id, holder, amount, vest_start, vest_end, contract })

Declare supply allocated outside the sale. Who signs: the declaration's venue

lab_prepare(8462, "declare_liquidity", { declaration_id, liquidity_locks, lock_id, lender, asset, financed, due_at, contract })

Declare the lock holding the liquidity, and its financing. Who signs: the declaration's venue

lab_prepare(8462, "declare_fee_recipient", { declaration_id, fee_rights, recipient, contract })

Declare where creator fees are accounted and who receives them. Who signs: the declaration's venue

lab_deploy_prepare(8462, "declarations", { launch_directory })

Your own LaunchDeclarations over a directory.

lab_check_contract(8462, chain, address)

The conformance read of any contract, on testnet or mainnet: supportsInterface and the views.

lab_feedback_draft(8462, note, txHash?)

The report text and the thread and issue links. It posts nothing.

A prompt to copy

Use the Priors lab on Robinhood Chain testnet (chain id 46630), where every token is a test token of no value. Its MCP server is https://lab.priors.trade/mcp and this draft's page is https://lab.priors.trade/erc/8462.md. Try ERC-8462, Token Launch Declarations (a draft under review). Start with lab_setup for my testnet address to see my test ETH, test dollars and identities, then launch a test token in one transaction: token, pool, liquidity lock, declaration, fee stream, then let the lab launchpad take a lab loan's principal for the pool, then declare a launch as your own venue, then declare supply allocated outside the sale, then declare the lock holding the liquidity, and its financing, then declare where creator fees are accounted and who receives them with lab_prepare(8462, <action>, params). Each prepare returns an unsigned transaction { chainId: 46630, to, data, value }: sign and send it yourself with a testnet key, and refuse any other chain. Never ask me for a key. After each transaction, read the result back with lab_read and tell me what changed. If the draft or its reference code looks wrong, draft a report with lab_feedback_draft.

Check a contract

Paste any contract on either chain: the lab reads supportsInterface for ILaunchDeclarations 0x84164db3 (computed from the pinned interface) and ERC-165's own, then calls each view. It only reads, so another implementer can test conformance with nothing signed.

Feedback

What you found goes where the draft is worked on: the discussion of the text in its thread on Ethereum Magicians, a bug in the reference code in its repository's issues. You post it under your own account. The lab posts nothing for anyone.
