plan to integrate testnet4

[ordinariusprof]

since testnet3 is unusable, is there a plan to utilize testnet4 as discussed here: bitcoin/bitcoin#29775 ?

as an aside to this, I saw today that the latest version of Sparrow (v1.9.1) has integrated testnet4 https://x.com/SparrowWallet/status/1790312602918126026

We'll definitely run it as soon as it is in a release version of Bitcoin Core

@raphjaph Do you have plans for releasing support for testnet4? Bitcoin Core 28.0 was released recently.

[raphjaph]

As soon as I merge #3962 ord will be compatible with v28

@raphjaph I just tried running ord on testnet4 but bitcoind uses port 48332 by default. Setting that to 18332 results in this error:

Oct 23 01:43:12 testnet4-deployment sh[30535]: error: Failed to connect to Bitcoin Core RPC at `127.0.0.1:18332/`:  JSON error: invalid value: string "testnet4", expected bitcoin network encoded as a string

Might be an issue you'll need to reopen this for. Build hash was: ef2212b

You'll have to change some parsing logic in the code, we look for testnet3 in places instead of testnet4. We're not going to officially support testnet4 until next year because we only want to support one testnet

testnet3 transactions fee are >4000 sats/vB, making it unusable because there are no faucets that give enough sats.
I've moved to testnet4, but now I need ord or unisat.io or ordinals.com to support testnet4.
I tried search-n-replace of testnet3 to testnet4 but the error persists.

Does anyone have a fork of ord that supports testnet4 today?

[raphjaph]

you could also try signet. If you drop me a signet address I'll send you some sats

[donnlee]

Oh awesome idea. Thank you!
And it seems ordinals.com supports signet, https://signet.ordinals.com
