myBTC is yield-bearing Bitcoin, built for Bitcoiners and Bitcoin treasuries: one deposit puts capital to work across two engines — Mezzamine Credit + Bitcoin Solver — with no further action required. For the case behind the denomination, see Why BTC-denominated.

​
The two engines

Mining credit

Powered by Mezzamine Credit — secured ASIC and hashrate loans to vetted miners, repaid from block rewards. This is myBTC’s core yield engine.

Bitcoin liquid vaults

Intent solver settlement and a liquid reserve blend into 2–4% BTC APY. This sleeve holds the liquidity that funds each 30-day redemption epoch and absorbs capital between mining-credit loan cycles.
All yield figures are indicative BTC APY ranges, not guarantees. Actual returns vary by program, market conditions, and counterparty. Figures are net of fees and BTC-denominated. Past performance is not indicative of future results.

​
The lifecycle

Deposit and redemption are always Bitcoin-denominated, and the allocation between the yield sources automatically rebalances as loan demand changes to maximize active yield generation:
1

Deposit BTC

Deposit native Bitcoin and mint myBTC 1:1 at the current mNAV.
2

Blended allocation

Capital splits across the two engines — mining credit and liquid vaults.
3

Dynamic rebalance

Allocation rotates toward mining credit as loan demand rises, and back toward liquid yield when it doesn’t — capital stays productive either way.
4

Redeem to BTC

Request a redemption at any time. Requests settle in 30-day redemption epochs, burning myBTC for Bitcoin at the accrued mNAV, funded from the liquid engine.
The custody option chosen at deposit holds through redemption; available options depend on the vault.
mNAV is the single number that expresses myBTC’s value in Bitcoin: no rebasing, no separate yield token, one exchange rate that moves as the pool earns.
mNAV is the exchange rate tracking the net asset value of the pool backing myBTC. As the pool earns yield, mNAV appreciates each epoch, so a fixed amount of myBTC is redeemable for more BTC over time.
A myBTC balance never changes on its own. Value accrues entirely through the exchange rate:
  • Deposits mint at the current mNAV. BTC in, myBTC out.
  • Redemptions burn at the accrued mNAV. myBTC in, BTC out, settled at the close of each 30-day epoch. Yield earned since deposit is captured automatically.
  • Distributions auto-compound. No payouts to collect; yield is reflected directly in mNAV.
  • Positions are transferable. myBTC can change hands on secondary markets — an exit route independent of vault redemption, priced against mNAV.
myBTC holds to a single-token model — yield accrues directly to the token held, with no separate yield token to manage.

​
Redemption epochs

myBTC has no lockup and no fixed tenor. Redemption runs through a queue that settles in 30-day redemption epochs:
  • Request at any time. A request joins the queue for the next epoch, and the position keeps accruing yield while it waits.
  • Settle at the accrued mNAV. At the close of the epoch, queued myBTC burns for BTC at the accrued mNAV.
  • Genesis positions are senior in every epoch. Allocators in the pre-launch Genesis Allocation retain redemption priority for the life of their position. The priority belongs to the account, not the token, so it does not travel with a transfer. The rest of the queue clears first in, first out.
For an exit between epochs, a transferable position can be sold on a secondary market instead.

​
Oversubscription

When deposits exceed available Mezzamine loans, the excess flows into the liquid vaults rather than sitting idle; as new mining loans open — typically at a higher BTC APY — capital rotates back into mining credit. Every deposited BTC stays deployed, and the blended rate tracks the current mix. myBTC blends the two engines into one position rather than requiring separate allocations to each vault in the directory.
