Skip Go Fast (`Instant Deposit`)

Skip Go Fast is a decentralized bridging protocol, developed by Skip, that enables rapid and secure cross-chain transactions across major blockchain ecosystems such as Ethereum, Cosmos, and Solana. Go Fast accelerates cross-chain actions by up to 25 times, reducing onboarding times from 10+ minutes to seconds. Learn more here.

Process Flow (Deposit)

Connect your wallet to the dYdX interface and navigate to the "Deposit" section
Enter the amount you wish to transfer (ensure it meets minimum requirements)
Choose the source chain and asset you wish to deposit
Review the transaction details including estimated fees and finality time
Confirm and sign the transaction from your wallet
Skip Go Fast protocol's solvers monitor for confirmation of fund arrival at Noble
- This process relies on Skip's decentralized solver network
- If your source token is not USDC, an automatic swap occurs via integrated DEXs
Once confirmed, funds are automatically sent to dYdX Chain via IBC transfer
- This step uses IBC relayers to complete the cross-chain transfer
Final step Funds are moved from the main account to the subaccount for trading
- This internal transfer is handled by dYdX Chain’s infrastructure

How Skip Go Fast Works

Skip Go Fast uses a solver-based approach to achieve near-instant finality:

User Intent Submission

When you initiate a transfer, you call the submitOrder function on the protocol contract
This broadcasts your intent to transfer assets across chains
Your intent specifies the assets, destination address, and any additional message payload

Solver Network

Permissionless participants called "solvers" watch for these intents
Solvers evaluate whether they can fulfill your intent based on:
- Their available liquidity on the destination chain
- Potential reward for fulfilling the intent
When a solver agrees to fulfill your intent, they use their own capital to front the assets

Instant Fulfillment

The solver calls the fillOrder function on the destination chain
This transfers the specified assets and processes any additional actions
From your perspective, the assets appear on the destination chain almost instantly

Settlement Process

After fulfilling your transfer, the solver initiates settlement to recover their fronted assets
The protocol verifies the solver's actions via a cross-chain messaging system
Once confirmed, the solver receives their assets back plus any earned fees
This settlement happens in the background and doesn't affect your user experience.
