## Coins, payout schemes and fees

| Coin | Payout scheme | Pool fee | Minimum payout |
|---|---|---|---|
| BTC | FPPS | 2.5% (0% when mining with Braiins OS firmware) | 0.0002 BTC on-chain (free from 0.005 BTC); 1 satoshi via Lightning |

## Payouts

| Parameter | Details |
|---|---|
| Payout schedule | Payouts are created daily at 09:00 UTC; on-chain payouts usually confirm in 1–2 hours, Lightning payouts within minutes. |
| Payout scheme explained | FPPS: every accepted share earns a share of the block subsidy plus average transaction fees, calculated once per UTC day. |
| Transaction fees | Transaction fee income is shared with miners; on-chain payouts below 0.005 BTC cost 0.0001 BTC. |
| Lightning payouts | Payouts can be sent over Lightning (up to 0.005 BTC) to a wallet with a Lightning Address, or withdrawn manually by invoice once per 24 hours. |
| Solo mining | Separate solo service (no registration): the block reward goes straight to the miner's address; 0.5% is kept for the CKPool software authors. |

## Connecting

| Parameter | Details |
|---|---|
| Server regions | One address, stratum.braiins.com (ports 3333 and 443); servers worldwide are selected automatically by location. |
| Stratum V2 | Supported with Braiins OS firmware; the URL carries the pool's public key to block man-in-the-middle hashrate theft. |
| Supported hardware | SHA-256 ASIC miners; GPU, CPU and phone mining are not supported. |
| Account needed | Yes for pool mining (username.workername login); solo mining needs no registration. |

- Access profiles give full, read-only or limited read-only access, including anonymous watcher links.
- A payout setup lock can stop anyone with account access from changing payout settings.
- The pool warns that it offers no cloud mining or investments and that staff use only braiins.com email addresses.

| 2022 | Slush Pool was renamed Braiins Pool. |

## Risks and caveats
