No existing bridge supported our source chain out of the box. Custom consensus. Non-standard token. We had to evaluate four completely different architectures to move a native token to EVM destinations. This is the comparison we built for ourselves.
Every cross-chain bridge design redistributes risk. It doesn't remove it. After reviewing dozens of integrations and one $3M exploit up close, here's how the four main approaches actually behave when real money moves through them.
The CrossCurve incident didn't surprise me. What surprised me was how many teams looked at it and said 'that wouldn't happen to us' — without being able to explain why.
We built multichain account abstraction, shipped it, then discovered MPC solves entire categories of problems our smart contracts couldn't touch. Here's the production reality.
After shipping ERC-4337 to testnet, we hit a wall. Not a technical limitation — an architectural one. Standard account abstraction assumed the account was a black box. Modular accounts turn it inside out.
The moment you try to recover a smart account on a chain where it hasn't been deployed, you hit a wall. This isn't theoretical.
