Yes, our https site supports Tor users. Our mainnet production site is at http: For the time being, you can exchange your money using bank transfers and sometimes debit or credit cards via an intermediary like a Bitcoin exchange or a broker.
There are also online services and communities where you can arrange to exchange cash for Bitcoin. This is an area of rapid change and innovation and so we do not list or specifically recommend any services in this space.
The best service for you depends on many factors. We suggest you locate local services using your favorite search engine and carefully review any potential options.
You should see new transactions in your wallet within seconds of it being sent by the payer. If you can not see your transaction in a block explorer, it probably means it is still propagating or failed to do so for example, setting the fee too low can cause transactions to be dropped.
We have sensible rate limits to prevent the service from denial of service attacks. It is extremely unlikely that a user will encounter these limits under normal use.
If you find that you are hitting a rate limit, please contact support with the details. If you have a requirement that exceeds the current limits, please feel free to contact us to discuss your needs further.
Addresses change constantly for privacy and security reasons. Re-using old addresses makes it easier for others to group transactions together and can be less secure.
While GreenAddress does correctly process multiple payments to the same address, we recommend not re-using them. Addresses should be thought of as one-time receipt IDs rather than as unchanging identifiers such as traditional bank wire details.
Please see the API documentation for more details. All previously generated addresses are available in the Receive tab under Advanced Options when using the Chrome or Cordova wallet clients.
Your private keys are not stored. They are derived on demand from your mnemonics as a seed to a BIP32 hierarchical wallet.
Your mnemonics and private keys are never sent to the server. The server receives the public key and chaincode for generated addresses only.
When you create a PIN, a random bit AES password is created and used to encrypt your mnemonics and store them on your device in encrypted form.
This password is sent to the server and destroyed on the client. If the server is given the correct PIN when logging in, it will return the password to the device in order to decrypt the mnemonics.
If the server is given the wrong PIN three times, it will destroy the password at which point the user must use their mnemonics to log in.
Note that the server never sees your mnemonics at any point. Your wallet client will then ask you to login using your mnemonics and you can resume using the service as normal.
The service never knows your mnemonics or passphrase; We cannot help you recover them if they are lost. If you have a wallet with PIN entry enabled, you can use your PIN to log in to the wallet and then view the mnemonics from the settings menu.
You should then write them down and store them safely. In all other cases you will only be able to retrieve your mnemonics by brute force trying various combinations of valid words.
This is similar to how a hacker might try to break into your wallet, and is not generally feasible. You should research third party services for wallet recovery, as GreenAddress does not offer assistance or support for wallet cracking for obvious reasons.
You should always have at least two different two-factor options enabled. As long as you keep these backups you can maintain access to your coins even if you lose access to one method for any reason.
In cases where you have lost access to all of your two-factor methods, we have no way to return control of your coins to you. We follow the restrictions that you placed on your account without exception.
If your coins are in a 2of2 account then you will need to recover your authentication - we cannot disable it in this or any other case.
Alternately, if you had enabled nLocktime transactions then you can use them to recover your coins after the nLocktime expires 90 days by default.
If you transferred your coins to a 2of3 account then you can move them without two-factor authentication since you have 2 of the 3 required signatures.
If not, then unless you can recover your authorization we cannot help you. As noted, 2of3 accounts can be used to avoid requiring authentication also.
These future mitigations require careful design and development to ensure that they cannot be exploited by attackers. It may be some time before we can safely implement them.
Our two-factor authentication system is a security measure that we include to ensure that even if a malicious party steals your mnemonics, they cannot access your wallet and steal your funds.
We do not do this, because if we did so, it would compromise all the security offered by 2FA in the first place.
Any malicious party could steal your mnemonics, and then contact us asking us to reset the 2FA, and then they could access your funds.
As such, we strongly urge users to set up at least 2 different 2FA methods. SMS delivery is not perfect and sometimes there can be delays or failures.
Some countries can be more affected than others depending on factors like the reliability of the underlying mobile infrastructure.
You should always have at least two two-factor methods enabled to maintain access to your coins. Email delivery is not guaranteed and sometimes there can be delays or a failure in delivery.
It is also possibly for anti-spam systems to mistakenly classify two-factor emails as spam or strip the attachments from them.
Please ensure you check your spam folders and give the email time to arrive. If you regularly have issues receiving email you may wish to adjust your spam settings, whitelist the sender in your client, or move to a more configurable provider.
GreenAddress is designed to allow you to recover your coins if the service ceases to be available. Using the PGP software you should verify that the packages you have downloaded have been correctly signed by us.
GreenAddress does not currently charge fees for any of its services. If we add a fee for any service in the future, this will be clearly communicated and opt-in.
Enterprise clients and those seeking custom solutions are welcome to contact us to discuss arrangements for extra services and support.
The fee you see in the sending transaction dialog is paid to Bitcoin miners to confirm your transaction i. Transactions fees change according to demand on the Bitcoin network.
Miners may ignore or delay transactions with extremely low fees. GreenAddress automatically calculates a fee that aims for your transaction to be mined quickly.
We do not aim for the absolute fastest possible confirmation time since doing so may be very expensive. Most of our wallet clients allow you to change the fee.
This can be useful if you want to ensure a transaction confirms even more quickly by increasing the default fee , or to lower the fee if you do not care how long the transaction takes to confirm.
Unless you are experienced in using Bitcoin, we suggest you use the default fee calculated for you by the wallet.
All GreenAddress wallets provide a confirmation dialog with fee information and a payment is generally denied if the amount is below what the network will accept.
When you send a transaction a fee is included as a reward to the miner that mines the transaction into a block see above.
If the fee is set too low the transaction can become stuck because the incentive is not sufficient for a miner to mine it.
In this case it is possible to replace the transaction with one with a higher fee. This is called "bump fee" in the client, and is also known as "replace-by-fee" or "RBF".
We have two Android applications, a native application and a Cordova application. Our iOS application is available from the iTunes Store.
All of our applications are open source and you can contribute to their development on GitHub. If you are building a service that will use GreenAddress, we suggest you get in touch to discuss your requirements and ensure your use of the service will be secure.
You can try our testnet version at test. A testnet faucet to receive coins for testing is available at tpfaucet. Please remember to send any testnet coins back to the faucet when you are done testing.
We also have a bleeding edge regtest environment and faucet available at regtestwss. This environment is updated regularly and may be restarted without notice.
We value your feedback and suggestions. Please feel free to raise issues on GitHub or email us at info greenaddress. We have a long list of planned features and languages that we wish to support.
