The short answerFor moving modest amounts between rollups, Orbiter is consistently the cheapest and fastest option, with no protocol exploit on record. The mechanism is a market maker sending you funds after receiving yours — there is a dispute process, and fundamentally it is a trust relationship.

What we liked, and what fell short
Liked- Very low flat fees and fast settlement between L2s
- No exploit of the protocol to date
- Simple, focused product
Fell short- Relies on maker solvency and honesty rather than cryptographic guarantees
- Coverage is limited to Ethereum rollups and a few others
Why the marks landed where they did
Orbiter does one thing: cheap, fast transfers between Ethereum layer-2s. A user sends funds to a maker's address on the source chain, and the maker sends the equivalent on the destination chain, minus a small flat fee.
The trust structure
This is not cryptographic bridging. It is a market maker fulfilling an obligation, backed by collateral and a dispute mechanism that can compensate users if a maker fails to deliver. In practice makers deliver because their business depends on it. In principle a maker could fail, and the dispute process is the recourse.
Why people use it anyway
Fees are a fraction of a dollar and transfers complete in under a minute — considerably better than canonical bridges and cheaper than most alternatives. For a user moving $200 between Arbitrum and Base, the trust assumption is proportionate to the amount and the saving is real.
Limits
Transfer sizes are bounded by maker capacity, coverage is essentially Ethereum rollups plus a few others, and there is no protection against sending to the wrong address or exceeding limits — mistakes here are user-recoverable only through support.
Who should use it
Users making frequent small transfers between rollups. For large amounts, use a canonical bridge or a protocol with cryptographic verification.
FAQ
How does Orbiter work?+
A market maker receives your funds on the source chain and sends the equivalent on the destination chain, minus a small flat fee, backed by collateral and a dispute process.
Is Orbiter safe for large transfers?+
It is designed for modest amounts. Larger transfers should use a canonical bridge or a cryptographically verified route, since Orbiter's security is maker solvency plus a dispute mechanism.
What does Orbiter cost?+
A small flat fee per transfer, typically a fraction of a dollar, making it the cheapest option for rollup-to-rollup movement.
Has Orbiter been exploited?+
No protocol exploit is on record.
