Sending money to a person online should be one action, not a checklist of addresses, networks, and confirmations. Almacy turns "send money to a person" into a single real transaction on chain 4663. Here is how the pieces fit together.

Send money to a person

On Almacy the destination of a payment is a person, addressed by their X handle. You send to @alice, not to 0xa39f4c. The handle resolves to her wallet, and the transfer settles on-chain.

There is no intermediate step where you look up an address, paste it, and hope you got it right.

One chain, two assets

Almacy keeps the surface small on purpose. There are two assets, USDG and ETH, and one chain, Robinhood Chain, chain id 4663. That is the whole map you need to hold in your head.

  • USDG for spending and settling in a stable unit.
  • ETH for everything that prices in ETH.
  • One network, so there is no bridge to pick and no chain to switch.

The flow: connect, wallet, pay

Getting to your first payment is three steps:

  • Connect X. Signing in with X is how you get in.
  • Get a wallet. A custodial wallet is created on first sign-in, with no seed phrase, and the signing key never reaches your browser.
  • Pay by handle. Enter a handle and an amount; Almacy resolves it and settles the transfer.
Connect X, get a wallet, pay by handle. Send to @alice, not to 0xa39f4c.

Real, public transactions

Every transfer on Almacy is a real, public on-chain transaction you can look up. It is not shielded, anonymised, or hidden. Almacy makes payments simple, not secret.

Balances are read live from Robinhood Chain. Nothing is seeded, nothing is simulated. What the app shows you is what the chain says.

Deposits and withdrawals

Your funds stay yours to move. Deposit from any wallet or exchange you already use, and withdraw to any 0x address you control.

  • Deposit USDG or ETH from an existing wallet or an exchange.
  • Withdraw to any 0x address whenever you want.
  • Custody covers signing, never the exit. The door out is always open.
