How to Deposit?

Target Users

This section is intended for users who wish to deposit their YBTC.B or BTC assets into the Vault to earn BTC-denominated yield. It applies to all supported blockchains (e.g., Sui, Avalanche, Plume, Starknet) and both Vault types (DeFi Vault and CeDeFi Vault).


Asset Options

You may deposit using either of the following:

- YBTC.B

  • Requires token approval before deposit (default is unlimited).
  • Upon deposit, users receive a Vault Proof Token (e.g., AvaxYBTC.B) representing their share.
  • Initially, deposits are 1:1, but the rate updates after each yield distribution.

- Bitlayer Native BTC

  • No approval needed.
  • BTC is automatically converted to YBTC.B during the deposit process.
  • Converted YBTC.B is then deposited into the selected Vault.

Step-by-Step Guide

  1. Visit the official Vault platform or a supported partner interface.
  2. Select the Vault product you want to participate in.
  3. Choose the asset to deposit: YBTC.B or Bitlayer BTC.
  4. (Optional) Click [Max] to autofill the max depositable amount:
    • For BTC, reserve a small balance for gas fees.
  5. Confirm the transaction.
  6. Upon success, a Vault Proof Token will be issued to your wallet.

Deposit Limits & Quotas

  • Some Vaults (e.g., Sui) may have fixed capacity limits.
  • If the cap is reached, further deposits will be blocked.
  • If your deposit exceeds the quota, the system will display a warning.

How to Determine Ownership?

Proof Token: Vault Ownership Certificate

After staking BTC assets (as YBTC.B), the Vault system mints a Proof Token representing your ownership and claim to future returns.

Functions:

  • Records amount staked, deposit timestamp, and expected yield.
  • Sole certificate for redeeming original BTC (or YBTC.B) + interest.

Proof Token Naming Rules

1. On-Chain DeFi Vaults

Proof Tokens are named by chain:

  • SuiYBTC.B
  • AvaxYBTC.B
  • PlumeYBTC.B
  • StarkYBTC.B

2. CeDeFi Vaults

TBD
