PRESALE & IDO CONTRACTS
Presale contracts that hold up when everyone shows up at once.
Whitelist gating, contribution caps, cliff and vesting schedules, and claim portals — built and load tested for the exact moment your presale opens.
Book a CallWhat's included
Whitelist & Allowlist Gating
Merkle proof or signature-based whitelisting so only approved addresses can participate — without gas-expensive on-chain lists.
Contribution & Cap Logic
Per-wallet and total raise caps, refund logic for over-subscription or failed raises, and pause and emergency stop controls.
Vesting & Cliff Schedules
Token release schedules enforced on-chain, matching whatever cliff, linear, or milestone structure your tokenomics define.
Claim Portal
A simple, load-tested claim interface so token holders can withdraw vested tokens without your team fielding support tickets.
Why this matters
A presale contract only has to work correctly once — under the highest load your project will ever see, with real money on the line. We test for that specific scenario: concurrent transactions, gas spikes, and cap edge cases — not just a clean testnet run.
