Documentation
Discreet bridging, documented.
Obsidian moves dollars into Robinhood Chainand lets you name the wallet that receives them. Here's everything you need to know before your first bridge.
What is Obsidian
Obsidian is a route aggregator — not a bridge of its own. When you move funds into Robinhood Chain, we ask several major bridges for a live quote at the same time and route you through whichever one pays out the most.
You always land on the best available price, and our platform fee is 0%. We don't move liquidity ourselves — we make the bridges compete and hand you the winner.
How it works
- STEP 01
Connect your wallet
Obsidian reads your active network and pre-selects a sensible source chain. Nothing moves without your approval.
- STEP 02
Choose an amount and a destination
We compare every route and pick the cheapest automatically — you don't have to pick a bridge. Leave the destination as your own wallet, or name any address on Robinhood Chain.
- STEP 03
Receive in seconds
Confirm in your wallet and your funds arrive on Robinhood Chain — usually within a few seconds.
How the routing is reported
Obsidian does not publish which routing providers it uses, and the interface never names one. What it reports is how many routes were priced for your crossing and what the winning quote was worth against the worst — the saving is stated as a number rather than asserted as a claim.
Routing
Every crossing is priced across each available route at the same time, and the best payout is taken automatically. Providers are not identified anywhere in the interface — by rank, by name, or by count of any individual one.
For some amounts a route may not be available: very small transfers can fall below a minimum. Those simply do not enter the comparison, and the number of routes actually priced is what the app reports.
Supported chains
Bridge in either direction between Robinhood Chain and the networks below.
| Direction | From | To |
|---|---|---|
| Deposit | Arbitrum, Ethereum, Base, Optimism | Robinhood Chain |
| Withdraw | Robinhood Chain | Arbitrum, Ethereum, Base, Optimism |
Robinhood Chain
Robinhood Chain is the destination network. A few quick facts:
| Chain ID | 4663 |
|---|---|
| Gas token | ETH |
| Explorer | robinhoodchain.blockscout.com ↗ |
You can add Robinhood Chain to your wallet in one click from the bridge — no special setup required.
Instant withdrawals
Withdrawals are instant. Because Obsidian uses intent-based routes, your funds arrive in seconds — there is no 7-day waiting period like the canonical bridge.
When you withdraw, the transaction happens on Robinhood Chain, so you'll need a small amount of ETH there to pay for gas. If your balance is razor-thin, top up a little ETH first. Obsidianchecks this for you before you confirm and will tell you if you're short — so you'll never get stuck mid-transfer.
What it costs
Obsidian charges a 0.00% platform fee. You only ever pay the winning route's own fee plus network gas.
Because we always route you through the cheapest option, bridging through Obsidian costs the same as or less than going to that bridge directly.
