igneum-labs dda5dedf44 Site reset to Igneum 2.0, first pass: /bench and /journey gone, no testnet, no 0.x history, the Igneum 2.0 devnet, the positioning line

- build.mjs no longer writes bench.html, journey.html or journey.json; the three files are deleted; /bench -> /evidence and
  /journey -> /live redirects (permanent: false); nav, footer, sitemap, capture routes and the site-nav-check groups drop them;
  link-check resolves literal vercel.json redirects and lists every link that leans on one (evidence.html: /bench, another hand)
- every testnet card, column, row, notice and link removed from the pages this lane owns; release manifest: the testnet entry
  gone, network igneum-devnet-4 "Igneum 2.0 devnet", the Devnet 3 genesis, digest, vote domain and floor lines dropped
- "Devnet 3" leaves every owned page; the devnet state is one constant in build.mjs (DEVNET_STATE, 'starting' now: the nav
  pill and the homepage badge read "Igneum 2.0 devnet starting"; 'live' flips both and re-enables the nav's live read)
- no 0.x release history: screenshot alt texts say the current build, the miner page's "Current build:" keeps the data-rm
  spans without the node version; miner-bench.json keeps the current-program rows only, no Counter ASIC names, no versions;
  /miners drops the earlier-classes table, the history note and the miner-version column
- /income keeps the calculator; the testnet-era tier tables (docs/analysis/income-tiers.md) are not served
- the positioning line is the first line of the footer partial (every page), the homepage meta description's first sentence
  and the hero's sub-line; share metas (site/og/pages.mjs) carry no Devnet 3 or zkEVM
- ledger-text-check is red on two index.html pins (X2, X31: the testnet sentences), owned by the ledger hand

Your first contract on the devnet, in five minutes

With Foundry. Tested end to end on a build box; the pass line and the exact output are at the end. Hardhat, ethers and viem work the same way: chain id 4464 and the RPC below.

0. What you need

Foundry: curl -L https://foundry.paradigm.xyz | bash && foundryup. About a minute.
The RPC. The devnet's public endpoint is https://rpc.devnet.igneum.network. A node you run yourself serves http://127.0.0.1:26790.
Nothing else. No account, no sign-up.

export RPC=https://rpc.devnet.igneum.network
cast chain-id --rpc-url $RPC          # 4464

1. A key, for the devnet only

cast wallet new

It prints an address and a private key. Keep the key for this walkthrough and nothing else: devnet coins have no value and the chain resets without notice.

export PK=0x...                       # the private key cast printed
export ME=$(cast wallet address $PK)

2. Coins from the faucet

Paste $ME into igneum.network/faucet. It sends 10 IGN and shows the transaction hash. Once per address per day.

cast balance $ME --rpc-url $RPC --ether      # 10.000000000000000000

3. Deploy

Foundry's template is a counter. Initialise it and deploy it as it is.

forge init counter && cd counter
forge create src/Counter.sol:Counter --rpc-url $RPC --private-key $PK --broadcast

Expected:

Deployer: 0x...
Deployed to: 0x...
Transaction hash: 0x...

export C=0x...                        # the Deployed to address

4. Call it

cast send $C "increment()" --rpc-url $RPC --private-key $PK
cast call $C "number()(uint256)" --rpc-url $RPC      # 1
cast send $C "setNumber(uint256)" 41 --rpc-url $RPC --private-key $PK
cast call $C "number()(uint256)" --rpc-url $RPC      # 41

cast send waits for the receipt. A block takes about a second.

5. See it

Paste the transaction hash into igneum.network/explorer. The receipt is also one call away:

cast receipt 0xTXHASH --rpc-url $RPC

What is different under the hood

Gas has two dimensions, execution and proving. The node folds the second into the price it quotes, so forge and cast estimate and pay as on Ethereum. igneum_estimateGas shows both numbers and whether a call exceeds the proving limit.
Your transaction is in a block within about a second, proven tens of seconds later, and locked by miner signatures in about two minutes. igneum_getTransactionStatus reports each stage.
A transaction signed for another chain id is refused. EIP-155, EIP-1559 and legacy envelopes are accepted.

The test record

Run on a build box against its own devnet node (the box that also fronts the public RPC and runs the faucet), with Foundry 1.8.5 and a fresh key, through docs/build/first-contract-test.sh. The pass line is appended below by the run.

PASS 10:17:23Z: devnet chain id 4463, faucet drip 0x8620e9d894484e824e4ac33002946a00e2f75823ea6db0da0ad29f1af142e8f2, deployed Counter at 0x6345265C6Db0b3713eb6645d795d0B52FE0a4201 (tx 0xcf77b4822d51f3c60ecdf6d7dbbe67524d42071f06c76e1cf9b0511d64783574), increment then setNumber(41) read back 41, receipt status 1 (success), block 27055, 24 s end to end, Foundry 1.8.5

Through the public endpoints, https://rpc.devnet.igneum.network and https://faucet.igneum.network, from the box: the first faucet drip and the first reader-path deploy on the devnet.

After the class v5 floor moved the chain id to 4464 the same afternoon, from a second box:

PASS 12:38:39Z: devnet chain id 4464, faucet drip 0xa54fdb7e964dab095aaccaab36ea548fc3fa8727acb809b593c2d4d1359c233f, deployed Counter at 0x7de503a4F39feEBCE8c4ABbAcC04282EE75120Fe (tx 0x6ccdbb4f6393fcf09e58ba2f4de1af98c547eeab6f02d93eacfebae883200dc6), increment then setNumber(41) read back 41, receipt status 1 (success), block 29878, 12 s end to end, Foundry 1.8.5
