A builder's journal documenting the development of MolePin (MOL) — a fixed-supply omnichain MemeFi token, live across 7 EVM chains via Chainlink CCIP, built and operated solo.
The failures are in here on purpose. So is everything I'd do the same way again.
Every design decision serves a single invariant: the total supply of MOL, across every chain, always equals 6,942,420,888,888. Bridging moves MOL between chains. It never mints new MOL out of thin air, and it never destroys it.
BSC is the home chain and holds the entire fixed supply via a LockRelease pool. The six remote chains — Ethereum, Polygon, Arbitrum, Optimism, Base, Avalanche — run BurnMint pools that mint on arrival and burn on departure. The amount locked on BSC always equals the total circulating across the remotes.
Long-form engineering essays — the stories behind the build.

|---|---|---|
| 01 | I Rebuilt Everything After the Audit | Why I threw away the deployment and redeployed clean after Beosin |
| 02 | Why I Left LayerZero for Chainlink CCIP | Not a technical verdict — an operating-model one for a solo builder |
| 03 | The Same Code Behaved Differently on Every Chain | Multi-chain deployment as an accounting problem |
| 04 | The Decisions I Made Before Listing | Honest FDV, V2 over V3, and the path from one key to a multisig |
Shorter technical notes — single ideas, quickly told.
| Note | What it covers |
|---|---|
| The BSC USDT Decimals Trap | 18 decimals on BSC vs 6 on Ethereum — off by 10^12 if you assume |
| Two Kinds of Priming | prime-remote vs prime-gateway — two slots, two penalties |
| Why EVM First, Non-EVM Later | Depth before breadth — sequencing TON, Tron, Solana |

The token economy is audited by Beosin (Report No. 202606191626). Twenty-one contracts — tokens, gateways, and pools across all seven chains — are source-verified on every block explorer. The bridge has been tested live in every direction, and the supply invariant has been checked transaction by transaction.
Contracts and tests live in molepin-contracts. This repo is the story of building them.
Read the series. Verify the contracts. Add up the supply yourself. — Roy
