It is recommended to omit salt from
The salt will be deterministically calculated from the account and bid parameters,
so it does not need to be remembered later during the
All operations which require transactions on the network have all useful information dumped to ens-log.txt.

To operate on the Ethereum blockchain, you first require an account. This will create a new account for you.
You may also use any standard JSON wallet from Geth or Parity.
/Users/ethers> ethers-ens init account.json Initializing a new JSON wallet - account.json Keep this password and file SAFE!! If lost or forgotten it CANNOT be recovered, by ANYone, EVER. Account Password: ****** Confirm Password: ****** New account address: 0x3A9ffB4E5A9C0226ac28B18A9F419C033aD9f0A7
This can be used to check the address and current balance of an account, as well as optionally check the password to make sure the file has not been tampered with.
/Users/ethers> ethers-ens --testnet info account.json Network: testnet Address: 0x3a9ffb4e5a9c0226ac28b18a9f419c033ad9f0a7 Balance: 1.23456 /Users/ethers> ethers-ens --testnet info account.json --check-pasword Network: testnet Account Password: ****** Password OK!

Before starting an auction or bidding, you should check its current status.
Once a domain is owned, this can also be used to inspect it.
/Users/ethers> ethers-ens --testnet lookup ricmoose.eth Network: testnet ricmoose.eth State: owned Available Start Date: 2017-04-22 07:06:06 (18:08:12:44 ago) Winning Deed: 0x87D2BE74Ce665dB345fF46Bf5e4ed8274FBEAF41 Winning Bidder: 0xf770358c6F29FAA38186E49c149C87968775B228 Value: 0.01 Highest Bid: 0.02 Owner: 0xf770358c6F29FAA38186E49c149C87968775B228 Resolver: 0x4C641FB9BAd9b60EF180c31F56051cE826d21A9A Address: 0xf770358c6F29FAA38186E49c149C87968775B228 /Users/ethers> ethers-ens --testnet lookup testing.eth Network: testnet testing.eth State: open Available Start Date: 2017-04-28 22:28:48 (11:16:55:00 ago)
To keep an eye on names (during
scan-log), add the name to the watch list.
/Users/ethers> ethers-ens --testnet watch pokemoose.eth Network: testnet @TODO
Once you are no longer interested in tracking a name (during
scan-log), remove the
name from the watch list.
/Users/ethers> ethers-ens --testnet ignore pokemoose.eth Network: testnet @TODO
Dump a summary of all domains being watched (any name which you have started an auction for, bid on or are watching), the current status, your bid, highest bid and value.
/Users/ethers> ethers-ens --testnet scan-log Network: testnet @TODO
Once an auction has begun, there are two important periods over the next 5 days:
/Users/ethers> ethers-ens --testnet --account account.json start-auction testing.eth Network: testnet Account Password: ****** Label Hash: 0x5f16f4c7f149ac4f9510d9cf8cf384038ad348b3bcdc01915f95de12df9d1b02 Transaction Hash: 0x5e4eb5c9a598be528c2a0b385a32da868262e25395635a0a14be8b4fa78478eb
When placing a bid, it is blinded; nobody can see what name the bid was made for, nor can they determine the exact amount the bid was for (since additional funds can be added to mask the true bid amount).
If a bid is not revealed during the reveal period, ALL FUNDS ARE DESTROYED. Make sure
if you bid, that you call
reveal-bid during the reveal period, even if you lost, to get
your funds back.
/Users/ethers> ethers-ens --testnet --account account.json bid testing.eth 0.01 --extra 1.0 Network: testnet Account Password: ****** Label Hash 0x5f16f4c7f149ac4f9510d9cf8cf384038ad348b3bcdc01915f95de12df9d1b02 Salt: 0x0fa811800a025edf58caf38f5a22c8888a7776f67b5da3b1de506ac365201102 Sealed Bid: 0x1778a8db6855506c49f1bd1477ca17ce89963fafc0cdd68adfa1210d0291c302 Transaction Hash: 0x48f80359f8237c66be15cc90372735b4b64f2333dd27a4f88360d61dae133a47
During the reveal period, everyone who placed a bid MUST reveal their bid, regardless of whether they won or lost. Faiure to do so will DESTROY THEIR FUNDS.
/Users/ethers> ethers-ens --testnet --account account.json reveal-bid ricmoose.eth 0.02 Network: testnet Account Password: ****** Label Hash 0x225fc58fd958ebe1205a9eb9a23c6fdb031e1d4fbfeba26468da16988e5ebf55 Salt: 0xa770059ab96c8810ad12ef3b27ebe9a37bb491e58c05845ca8aff6c234c4ff6d Sealed Bid: 0x5cc1bbfc5e508d7cd93808566430a5f2e8875a5f5ae884419edfc0f3712f8b6f Transaction Hash: 0xc3820b28d1ed2a9d7e3be90d4e9aaa8da57e60de9299489c09b9eb03290cac5f
Once the auction has ended, anyone can call finalize. This will perform the final assignment of the domain oner to the winning bidder. Usually the winner would be the one that would call this.
/Users/ethers> ethers-ens --testnet --account account.json finalize-auction ricmoose.eth Network: testnet Account Password: ****** Label Hash 0x225fc58fd958ebe1205a9eb9a23c6fdb031e1d4fbfeba26468da16988e5ebf55 Transaction Hash: 0x5c91c8c64fa9bad8668a5e2d0b7ae176d08654f928b647cdeb32cb40496620a7
Once you have won the auction, you must assign a contract which will resolve addresses and other queries made against your name.
The default public resolver can be set up using:
/Users/ethers> ethers-ens --testnet --account account.json set-resolver testing.eth Network: testnet Account Password: ****** Node Hash: 0xb52c4744695ed3be701ccef35d5901de3aaf7294245966ef16617c30aab7b626 Transaction Hash: 0x6cd76e91045d9cf8c27efa572c1e8d07887f91ea65ce21a53ccd4081df0c6463
If you have used the default public resolver (or a compatible resolver) the address your name should resolve to can be set using:
/Users/ethers> ethers-ens --testnet --account account.json set-address testing.eth 0x3A9ffB4E5A9C0226ac28B18A9F419C033aD9f0A7 Network: testnet Account Password: ****** Node Hash: 0xb52c4744695ed3be701ccef35d5901de3aaf7294245966ef16617c30aab7b626 Transaction Hash: 0x9fbb6f327621070a6f2d604927283383da53df2e989216fe3b2319ec8b53c485
More details coming soon. These API calls may change.
var ethers = require('ethers'); var Registrar = require('ethers-ens'); var provider = ethers.providers.getDefaultProvider(); // Read-only var registrar = new Registrar(provider); // Read/Write var privateKey = '0x0123456789012345678901234567890123456789012345678901234567890123' var wallet = new ethers.Wallet(privateKey, provider); var registrar = new Registrar(wallet);
A nanny (daemon) mode, which will watch for names to become avaiable, bid and reveal for you.
More (and better) documentation.
More concise gasLimits (so if there is a throw, less is at stake).
Dist files for the browser (and a demo ethers.io app).
Starbucks Frappuccinos were half price this week, so my out-of-pocket expenses were pretty low for this, but if you'd like to buy me a coffee anyway, I won't say no. :)
