About

Ember is a vault protocol where professional curators run on-chain and off-chain yield strategies. Users deposit a single asset and receive an ERC-4626 vault share token. Yield builds up in the vault's share price, so there is no separate reward token to claim.

Vaults currently available through the Yield API:

Vault	Receipt Token	Curator	Strategy
Ember Earn	eEARN	Ember	USDC hybrid strategy across fixed income, DEX liquidity, lending and rate carry
Bitwise Premium+ RWA	PPLUS	Bitwise	USDC looping strategy on real-world-asset credit
Syntetika BTC Hilbert Basis+	hBTC	Tulipa Capital	cbBTC allocated to Hilbert Group's BTC basis+ fund

The user flow:

Deposit: Users deposit the supported asset and receive vault shares. eEARN and PPLUS shares are minted instantly. hBTC deposits wait in a deposit queue until the next processing run (see Considerations).
Earn: Yield builds up in the share price.
Request withdrawal: Users submit a redemption request, and the position shows as an unstaking balance.
Settlement: Ember's vault operator processes the request and sends the underlying asset directly to the user's wallet. The user doesn't sign a claim transaction.

Considerations

Queued deposits (hBTC)

hBTC deposits are converted into vault shares twice a month, on the 13th and 28th. A deposit must be queued at least 24 hours before a run. While it waits, it shows as a preparing balance in cbBTC.

Queue-based withdrawals

Withdrawals are not instant. Requests are processed by the vault operator at the share price on the processing day, so the final payout may differ slightly from the estimate.

Vault	Typical withdrawal time	Withdrawal fee
eEARN	~3 days	0.05%
PPLUS	~7 days	0.1%
hBTC	~2 weeks	None

Eligibility

No KYC is required, but PPLUS and hBTC are not offered to U.S. Persons or in restricted jurisdictions. See Ember's Terms & Conditions and the Syntetika Terms of Service.
