Lightning splicing and merchant tools push Bitcoin payments mainstream
- Splicing protocol is ratified, enabling cheaper, simpler Lightning channels - Phoenix Wallet fees dropped 50%.
- Square automatically enables Bitcoin for millions of US merchants, shielding them from volatility and IRS complexities.
- Non-custodial wallets in apps like Primal remove KYC, giving users a default payment option at signup.
Bitcoin payments are shedding their technical friction. The Lightning Network's splicing protocol - finally ratified as BOLT 1160 after cross-implementation testing - is the core upgrade collapsing cost and complexity.
Splicing allows users to change a channel’s capacity without closing it, akin to changing a plane's wings mid-flight. According to Bitcoin Optech, this lets wallets like Phoenix manage a single channel per user, which halved fees and unified a previously fragmented liquidity mess. For large routing nodes, it more than doubles throughput capacity.
Dusty Daemon, Bitcoin Optech:
- Splicing at its core allows you to change the size of a Lightning channel.
- It is kind of like changing the size of the wings on a plane while it is flying.
Merchant adoption is accelerating through abstraction. David Bennett on Bitcoin And highlighted Square's recent shift, which flips Bitcoin acceptance from an opt-in to a default-on setting for millions of US sellers. The merchant receives dollars, while Square handles the Bitcoin conversion and IRS reporting, turning crypto into a background payment rail.
User-facing apps are integrating wallets by default to bypass regulatory friction. On Nostr Compass, Paul from the Primal team explained that integrating the non-custodial Spark wallet removed KYC hurdles and geographic blocks, giving users in countries like Canada immediate payment access upon download.
Paul, Nostr Compass:
- Having a wallet by default for every user without a setup is UX magic.
- It makes the whole pitch make more sense because we're all about not putting your data out there.
The pieces are aligning: a more efficient protocol layer, aggressive merchant rollout by fintech giants, and seamless wallet integration in social apps. The goal is for Bitcoin payments to become an invisible feature, not a novelty.
