Which chain does Meridian use?

Meridian’s current mainnet documentation identifies Robinhood Chain4663. Testnet46630 is separate, and the older Ethereal chain 5064014 is not the destination for this funding flow.

Do I need USDe or ETH to fund Meridian?

The documented collateral flow uses supported ERC-20 USDe. Robinhood Chain transaction gas uses ETH, so these are separate balances with different purposes.

What is merUSD in Meridian?

MeridianUSD (merUSD) is an ERC-20 settlement token described in the official integration guide. A supported USDe deposit is wrapped 1:1 into merUSD and credited to the subaccount; it is not the native gas token.

Can I send USDe directly to the Meridian exchange address?

Use the app’s Deposit flow. The official deposit documentation says a direct token transfer does not specify a subaccount and should not replace the deposit function.

Will my Ethereal balance or linked signer appear in Meridian?

No automatic carry-over is documented. Meridian is a separate deployment; the migration guide explicitly separates balances, subaccounts, approvals, identifiers and linked signers.

Does Sweep complete the Meridian deposit for me?

A Sweep swap or bridge can only be used where its current catalog and quote support the exact required wallet asset and network. Crediting a Meridian subaccount is a separate action in Meridian unless a current route explicitly includes that deposit.

How to fund Meridian on Robinhood Chain

Meridian is the successor venue referenced by Ethereal, with a separate deployment on Robinhood Chain. To fund a Meridian subaccount, hold supported ERC-20 USDe on the correct network, keep ETH for gas and use the app’s Deposit flow. A wallet transfer alone does not credit trading collateral.

Robinhood Chain: quick answer

Use Robinhood Chain mainnet 4663; Meridian testnet 46630 uses separate hosts and valueless test assets.
The documented deposit wraps ERC-20 USDe 1:1 into ERC-20 MeridianUSD (merUSD) and credits a subaccount.
Ethereal balances, approvals and linked signers do not automatically carry into Meridian; do not fund old chain 5064014 for this task.
The former Ethereal chain preset does not fund the new Meridian account.

Robinhood Chain: network and asset details

Current host network: Robinhood Chain mainnet
EVM chain ID: 4663
Gas: ETH
Deposit input: Supported ERC-20 USDe
Conversion: USDe wraps 1:1 to ERC-20 merUSD and credits the selected subaccount

Connect to Robinhood Chain mainnet

Check that the wallet and Meridian app are on mainnet 4663. Robinhood Chain uses ETH for native gas, separate from the USDe you intend to deposit.

Having ETH or USDe on Ethereum or another chain does not create a Robinhood Chain balance. If you need to move funds, select the exact destination network and supported token, then review the current route before proceeding.

Prepare supported USDe and ETH

Read the current Deposit panel before acquiring collateral. It identifies the enabled token and minimum amount; those settings can change. Match the supported token contract rather than relying on a ticker.

Use a supported swap or bridge only if it delivers the exact required asset on Robinhood Chain. Keep ETH for source actions and for the subsequent Meridian deposit. A same-chain wallet balance is preparation for the deposit, not trading margin by itself.

Deposit through Meridian rather than sending to its contract

Open the official Meridian app and connect the wallet that owns the collateral.
Select Deposit, a supported token and the destination subaccount.
Enter the amount and review any spending approval requested.
Confirm the deposit transaction and wait for onchain confirmation and app processing.
Check the subaccount balance before placing another deposit.

Understand USDe, merUSD and the subaccount balance

Meridian’s current documentation describes ERC-20 USDe backing ERC-20 MeridianUSD (merUSD). The documented deposit pulls USDe, wraps it 1:1 into merUSD and credits the chosen subaccount.

Do not send tokens directly to the exchange address: a direct transfer does not specify a subaccount. Use the app’s deposit function and check the resulting transaction and balance. The conversion into merUSD is also separate from any exchange conversion between quote-token pools.

Keep the owner wallet available for withdrawals

Use the owner wallet when withdrawing; a linked trading signer cannot authorize a withdrawal. Review available collateral and the displayed fee, then track the request through finalization.

Total balance and withdrawable balance can differ because of open positions, orders and fees. If a transfer remains pending, inspect its transaction and app state before repeating it. Old Ethereal account settings should not be reused as Meridian configuration.
