The reason why @Coinbase Commerce doesn’t support self-custody $BTC baselayer payments is simple

UXTO chains like Bitcoin lack the programmability necessary to meet the requirements of most merchants

1) Merchants don’t want to be exposed to crypto price volatility risk

Ethereum and EVM chains solve this by being able to programmatically covert whatever crypto token is used as payment into a stablecoin like $USDC, when can then be optionally redeemed for $USD and sent to the merchant’s bank account

UXTO-based chains like $BTC lack the native programmability to convert their native asset into stablecoins onchain, so a custodial solution is required

2) Merchants don’t want to deal with manual burden of resolving incorrect payments (eg: underpayment)

Ethereum and EVM chains solve this by being to programmatically reject payment with incorrect payment amounts

This is literally a single line of code in a smart contract (require payment amount == invoice amount, otherwise revert)

UXTO-based chains like $BTC lack the native programmability to revert payments based on amount, so a custodial solution is required

Net result is that Coinbase made a calculated decision that the overhead/friction/cost of supporting baselayer $BTC payments was simply not worth it

Payment processing for self-custodial wallets is challenging, it’s not nearly as a simple as just giving a customer an address to pay into, they will fuck it up, it needs to be idiot-proofed

Can lightning fix this for $BTC? Possibility, but there’s a great deal of friction today in terms of managing inbound/outbound liquidity and channel rebalancing

Lightning also means you can support one additional asset, $BTC, while integrating with EVM chains means you can accept hundreds to thousands of crypto-assets (including stablecoins and $WBTC) and get paid directly into your bank account programmatically if you desire

That said, I hope Lightning improves enough to make it a realistic option for merchants to leverage Additional context/commentary from the Coinbase Commerce team themselves about UXTO payment support:

Happy new year frens, welcome to 2024 🙌

Obligatory thread of some of my unfiltered thoughts and predictions regarding the major crypto trends this year

🧵 • Bitcoin as a Dominant Asset Class

The catalysts for $BTC are clear; a dozen or so spot ETFs a week from approval, halving in April, multiple interest rate cuts, and fiat money printer brrrrr

Initial ETF inflows won’t be as massive as expected but will ramp up over the year

A liquid restaking token that is backed by liquid staking tokens deposited in a restaking protocol which rehypothecates staked ETH

This is getting pretty deep, can we add another layer of liquidity and risk here? I don’t think we have enough

https://twitter.com/Shoalresearch/status/1736811526458421378

Note that there’s four+ layers of risk

1. Risk of staking ETH
2. Risk of liquid staking ETH
3. Risk of restaking ETH
4. Risk of liquid restaking ETH

You’re not only exposed to slashing and smart contract bug risk at each tier, but risks that only appear when composing protocols

"Chainlink is just an oracle"

What started as a single ETH/USD Price Feed has since expanded into a fully-featured platform of services

There are now 1,000+ #Chainlink oracle networks that span external data, offchain compute, and cross-chain interoperability

A thread 🧵 Oracles connect blockchains to external systems, enabling them to execute based on inputs/outputs from the real world

Before chainlink, oracles were highly centralized and insecure, with frequent oracle attacks resulting in exploits and loss of funds

Why does @PayPal launching a stablecoin $PYUSD on Etheruem matter?

Let’s dive in 🧵👇 1. $PYUSD shows there is clear demand from financial services companies to tokenize assets on blockchains

Tokenizing dollars is the most straightforward asset to tokenize, and is directly relevant for payment processors like @PayPal

What does this mean for the cross-chain ecosystem and what new capabilities does CCIP bring to the table?

Let's dive in 🧵👇 2/ Web3 today consists of hundreds of independent L1 chains, L2 rollups, appchains, sidechains, subnets, and more launching every week

To create a truly interoperable Web3 ecosystem, data and value needs to be able to move seamlessly between chains

This is where bridges come in

For Web3 to succeed, each layer of the Web3 tech stack needs to become economically sustainable

⛓️ Blockchains
📄 Applications
🔮 Oracles

In pursuit of this goal, #Chainlink is pioneering the creation of a sustainable oracle economy 🧵
blog.chain.link/sustainable-or… Web3 represents a global movement focused on replacing prone-to-failure trusted intermediaries with decentralized trust-minimized infrastructure

Despite the bear market and all the fear, development hasn't stopped, but actually increased

Web3 is inevitable

Both Ledger and Trezor can, in theory, publish signed malicious firmware updates that siphon keys from user devices (assuming users accept the firmware update)

This is simply a part of the trust model with hardware wallets with upgradable firmware But when the firmware is open source, it can be validated by the security community and alarm bells can be raised if there’s any funny business

If the firmware is closed source, it’s a black box and its capabilities cannot be verified, requiring full trust in the manufacturer

BRC20 is a very weird and inefficient token standard built on top of Bitcoin, ordinal theory, and NFTs

To mint a BRC20, you create a ‘mint’ NFT with the amount to be minted, in competition with others via a priority gas auction

A mega-trend is on the horizon for crypto

Tokenized real-world assets (RWAs) are now being issued on public blockchains by a growing number of Web3 projects and instituions alike

How and why?

This blog is my thesis on RWAs 🧵
blog.chain.link/tokenized-real… Firstly, why do people care about crypto and DeFi in the first place?

Because of the properties enabled by public blockchains:

- Atomic settlement
- Transparency
- User control
- Reduced costs
- Composability

Tens of billions of dollars have been absorbed into DeFi

It’s early 2022 and you want to earn some yield on your crypto, but you don’t want to get rekt so you diversify

You want some stability, so you put half your portfolio in the $10B stablecoin $UST and lend on @anchor_protocol for 20%

Nice, but you want directional exposure too You already have exposure to $UST and the ecosystem seems to be rapidly growing

So you get some $LUNA and stake it with @LidoFinance for 8%

You then deposit the $bLUNA to @anchor_protocol to leverage up

$UST is now a $20B stablecoin (and $LUNA $40B), you seem validated

The crypto ecosystem is quite bad at naming things, too much techno-jargon and acronyms

They're called cryptocurrencies, but most tokens aren't trying to be currencies

NFTs? No Fucking Thanks, I mean come on, just call them digital collectibles Smart contracts? They're neither smart nor contracts, decentralized applications is slightly better but they're really automated agreements

Gas? Let's not make the negative ESG narrative worse

LSDs? Let's not make the dark market connotations worse

1/ #Chainlink Staking v0.1 is launching tomorrow (Dec 6th, 12PM ET) 👀

What does this mean and what does Staking v0.1 look like?

Let’s break it down frens 🧵 2/ Staking is a mechanism where tokens are locked up in smart contracts to increase the cryptoeconomic security of a protocol

For Chainlink, this consists of $LINK being locked up as collateral to back the performance of decentralized oracle networks

The most bearish thing about DeFi is the seemingly complete lack of risk management that some dApps undertake

And with smart contract apps being so composable and interconnected, the risk is contagious and nearly systemic

Devs, circuit breakers, use them Btw proper risk management is not a “one and done” deal, it is a continual on-going process of creating, refining, and adjusting risk framework: and using them regularly to adjust parameters

Also having automatic monitoring systems in place as well as falsesafes
