SPL404 FORGE

Transaction v1 is live: 4,096 bytes per transaction

See what is really
inside the chain.

Paste any signature, address, or explorer link. SPL404 Forge asks Solana directly, decodes every memo, instruction, and account buffer in your browser, and shows you the images, files, and JSON hiding in them. Then it lets you put your own bytes there.

01 / Inspector

Trust the transaction, not the website.

Works on transactions, wallets, mints, and program accounts. Chunked files are rebuilt from their manifest and checked against their hash before anything renders.

Mainnet

02 / Forge

Make the chain your canvas.

Text, JSON, or a file. Anything too large for one transaction is split into chunks with a manifest, so it can be rebuilt and verified by anyone, forever, with no server in the path.

0 bytes · nothing to write yet

Network fees apply. On-chain content is public and permanent.

03 / Feed

What people just put on-chain.

Creations that opted into the public index, read live from Solana. The index is a program-derived address nobody controls, so this list needs no database.

Open by design

A microscope,
not a gatekeeper.

01

RPC native

Standard Solana JSON-RPC with transaction version 1 enabled. Point it at your own endpoint in settings.

02

Wallet controlled

Keys never reach this page. Your wallet shows and signs every transaction, and nothing is sent without it.

03

Verifiable

Chunked files carry a manifest and a SHA-256. A rebuild that does not match its hash is refused, not rendered.

04

Yours to fork

The parser, the protocol, and this page are open source. Read it, change the RPC, deploy your own.
