Why does PING look like an inscription? The rallying call of x402's narrative has already sounded.

Recently, the meme coin based on the x402 protocol called PING has become popular, with many saying it closely resembles the wave of inscriptions on BTC in 2023.

Does it look similar? Yes, it does. Will it replicate the development path of inscriptions? Most likely.

Core Similarities: On-chain Data + Off-chain Judge

Let’s first look at how inscriptions work.

You send a transaction on the BTC mainnet, occupying a specific UTXO, but BTC itself doesn’t know what you’re doing — it only handles bookkeeping. The real judge of whether “this transaction is a valid inscription” is Ordinals, a third-party indexer. It scans all records on the chain and, following the “First is First” rule, determines which are genuine inscriptions.

And PING? Almost the same formula.

You transfer USDC on the Base chain to a specific address (which is dynamically returned by x402scan). Neither the Base chain nor the x402 protocol knows you’re minting tokens; to them, this is just a normal ERC20 transfer.

The real decision-maker is the x402scan indexer — it scans all USDC transfers to the specified address on Base, follows the “1 USDC = 5000 PING” rule, decides which transfers are valid, then records the transaction off-chain and finally issues tokens via smart contract.

On-chain, only the raw transaction data exists. The interpretation power lies in the indexer off-chain.

Not Popular, but Can’t Stop It

Back when inscriptions first emerged, the Bitcoin Core team was unhappy — the BTC mainnet was filled with dust transactions, what’s the actual value? But as an open standard, BTC network couldn’t kick it out.

The same applies to PING. The x402 protocol was completely “free-ridden”:

All the USDC minted by everyone went into a treasury wallet designated by x402scan. The team crowdfunding and issuing tokens at the same time, while the x402 protocol was just used as a tool. Inscriptions still left some asset traces on BTC mainnet; if they stop, they can recover some BTC. But with PING? All assets are held in centralized wallets.

But don’t rush to criticize.

This is a “call to arms” experiment.

It forcibly created a usage scenario for the x402 protocol, and the effect was immediate — traffic increased, discussions started, and stress tests were conducted. To some extent, this is the singularity moment of the x402 narrative, which will push the protocol to improve, possibly spawning a wave of ecological prosperity.

Evolution Path: The Old Path of Inscriptions, Likely Repeated

The problems with PING are also quite obvious:

• Assets are held by centralized entities, contradicting the original purpose of the x402 protocol to “open payment channels for AI Agents”
• Compatibility with other x402 protocols is doubtful
• No unified standards for minting, transferring, or burning

These issues were also encountered in the inscription market back then. And then? BRC20, ARC20, SRC20, Runes… one after another, claiming to be more “orthodox.”

The x402 track will most likely follow the same path:

• Some improve custodial methods
• Some change the format of mint transactions
• Some seek native protocol layer support

Even if x402scan runs away one day or the treasury wallet is drained, this wave has already been set in motion. Pandora’s box has been opened, and it can’t be closed.

One last note: the explosion of x402 narrative is only a matter of time; PING has just sounded the charge.

How it evolves next is unpredictable. This analysis is meant to provide a cognitive framework and does not constitute any investment advice. But there’s no need to worry — the upcoming excitement is worth participating in.
