eCash (XEC)XEC

Amaury Séchet's Bitcoin ABC chain, split from Bitcoin Cash in November 2020 over a developer fund; renamed eCash in 2021. Not to be confused with Paul Sztorc's eCash (ECX).

Split

eCash began as Bitcoin ABC's side of the 15 November 2020 Bitcoin Cash upgrade. ABC's Infrastructure Funding Plan, which directed part of the block reward to development, was rejected by the majority, and ABC's chain became BCHA^[1][2]. The last common block was 661,647^[3]. It traded as BCHA until it was renamed eCash on 1 July 2021^[3][4].

Design

eCash keeps SHA-256d proof of work and adds Avalanche, a finality layer written by Bitcoin ABC: blocks have been finalized since 14 September 2022 and transactions since 15 November 2025^[3]. On Bitcoin Takeover, Amaury Séchet described it as a fork of BCH, and of Bitcoin by extension, with another consensus layer on top^[5]. Supply is the same 21 million coins in base units, displayed as 21 trillion XEC (1 XEC = 100 satoshis)^[3].

Funding

The block reward is split 58% to miners, 16% to Bitcoin ABC, 16% to the Global Network Council and 10% to stakers^[3].

Name clash

eCash (XEC) is a different chain from eCash (ECX), the 2026 Bitcoin fork associated with Paul Sztorc; ecash.com states plainly that the e.cash project uses the ticker XEC and that the shared name does not mean the same asset^[6].
