We are distributing tokens to about 120,000 wallets on Arbitrum and need a claim website. A visitor connects a wallet, sees whether it is eligible and how much, and claims with a Merkle proof. I will provide the final snapshot as CSV. You would generate the tree, host the proofs, build the page, and test the full flow on a testnet first. Gas costs, failed transactions and wallets that are already claimed must all be handled clearly.

The claim opens on a fixed date and we expect heavy traffic in the first hour.

Key Deliverables:

• Scoping, Setup & Test Environment: Reviewing the spec or existing setup, preparing a testnet or staging environment, and agreeing the plan.

• Implementation & Security Review: Completing the main work with tests, then reviewing keys, permissions, rate limits and failure cases.

• Production Rollout & Handover: Approved release to production, verification on explorer or monitoring, and a short runbook for the team.

Requirements:

• Demonstrated experience with React, Next.js, wagmi, Merkle Trees, Solidity

• Quick turnaround needed — must be available to start within 24 hours.

• Never ask for or accept private keys or seed phrases; work with read-only access, testnets and a multisig or the client's own signers.

• Mainnet deployment or production traffic changes only after we approve the result on testnet or staging.

• Source code and contract addresses must be verifiable by third parties (verified on the block explorer where relevant).

If you have experience with this type of project, we'd love to hear from you. Please include relevant work samples with your bid.
