FAQ
Solo or shared: which port should I use?
Solo (ECX 3335, BTC 3345): if your miner finds a block, you get that whole block minus 1%. Big but rare. Shared (ECX 3338, BTC 3348): every block found by anyone on that shared port pays everyone in the recent-shares window (PPLNS), in proportion to their work, minus 1%. Smaller but more often. Either way the reward is written straight to your address in the block: no pool balance, no withdrawals, no payout fees. On shared, a share too small to be worth a coin output (it would cost more than about 1% to spend) gets no output in that block; it keeps counting until a later block pays you. NerdOS miners can split hashrate, e.g. 90% solo and 10% shared.
Do I need a wallet address for every coin?
No. eCash, Bitcoin, Namecoin and Fractal Bitcoin all pay the key behind your bc1 address (on Namecoin, import that key or seed into a Namecoin wallet to spend it). Hathor is the exception: it needs its own H address, added in your password field. See Hathor.
What are eCash sidechain fees?
eCash (ECX) is a Bitcoin fork with Drivechains (BIP300/301): sidechains pay eCash miners to commit their blocks in eCash blocks. Those fees are part of the eCash block reward, so they go to miners like the rest of it, minus 1%. See the eCash page.
What does the 1% fee cover?
On every block paid to miners (eCash, Bitcoin, Namecoin, Fractal Bitcoin, Hathor), 1% of the reward goes to the pool's address inside the same coinbase, and 99% goes to miners. The pool never holds your coins.
Does merged mining slow down my eCash mining?
No. Your ECX or BTC odds are exactly the same. The merged coins come from the same work at no extra hashrate or power.
What are my odds?
Solo mining is a lottery: your chance of a block equals your share of that chain's network hashrate. Small miners should expect long waits and the full reward when a block hits, or use a shared port for smaller, steadier payouts.
Which address types work?
Use a bc1q… address (recommended). It works on eCash, Bitcoin, Namecoin and Fractal Bitcoin. bc1p (Taproot) and 3… addresses are not paid on Namecoin.
Is this an official eCash pool?
No. MergedHash is independent and not affiliated with ecash.com, LayerTwo Labs, or any merged coin project.
Questions? How do I reach the pool?
Email mine@mergedhash.com or join the MergedHash Discord (#support). Never send anyone your seed phrase or private keys: the pool only ever needs your public address.
Do I need to sign up?
No. Your payout address is your account. Point a miner at the pool with your address as the user name and it starts counting.
Which miners work?
Any SHA-256 miner that speaks Stratum V1: Bitaxe, NerdQAxe, NerdOctaxe, Antminer, Whatsminer, Avalon, and farm proxies. See the guides.
What is eCash (ECX)?
eCash (ECX) is a SHA-256 Bitcoin fork with Drivechains (BIP300/301). It split from Bitcoin at block 973,728 in October 2026. Bitcoin-style bc1 addresses and Bitcoin miners work unchanged. See the eCash page.
What is merged mining?
Other chains accept the same work as their own proof-of-work, so one share can mine eCash or Bitcoin plus Namecoin, Fractal Bitcoin and Hathor. Read what merged mining is.
Can I use rented hashrate?
Yes. Use the high-difficulty ports and a starting difficulty in the password. See rented hashrate.
Where can I see blocks the pool found?
On the blocks page, and pool health on the status page.
