## Introduction
Using this method, only transfer is possible between accounts that are generated in the same manner and that are yours. Please find the keygen tooling for it below.
## Prerequisites
### Keypair
- ed25519 keypair
- Go installed on your local computer
Create a keypair with the following tool:
```sh
go build .
./keygen
```
### Stellar to TFChain
Create a Stellar wallet from the key that you generated.
Transfer the TFT from your wallet to the bridge address. A deposit fee of 1 TFT will be taken, so make sure you send a larger amount as 1 TFT.
Bridge addresses :
- On Mainnet: `GBNOTAYUMXVO5QDYWYO2SOCOYIJ3XFIP65GKOQN7H65ZZSO6BK4SLWSC` on [Stellar Mainnet](https://stellar.expert/explorer/public).
- On testnet: `GA2CWNBUHX7NZ3B5GR4I23FMU7VY5RPA77IUJTIXTTTGKYSKDSV6LUA4` on [Stellar MAINnet](https://stellar.expert/explorer/public)
The amount deposited on TF Chain minus 1 TFT will be transferred over the bridge to the TFChain account.
Effect will be the following :
- Transferred TFTs from Stellar will be sent to a Stellar vault account representing all tokens on TFChain
- TFTs will be minted on the TFChain for the transferred amount
### Alternative Transfer to TF Chain
We also enabled deposits to TF Grid objects. Following objects can be deposited to:
- Twin
- Farm
- Node
- Entity
To deposit to any of these objects, a memo text in format `object_objectID` must be passed on the deposit to the bridge wallet. Example: `twin_1`.
To deposit to a TF Grid object, this object **must** exists. If the object is not found on chain, a refund is issued.
## TFChain to Stellar
Create a TFChain account from the key that you generated. (TF Chain raw seed).
Browse to :
- For mainnet:
- For testnet:
- For Devnet: https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Ftfchain.dev.grid.tf#/accounts
-> Add Account -> Click on mnemonic and select `Raw Seed` -> Paste raw TF Chain seed.
Select `Advanced creation options` -> Change `keypair crypto type` to `Edwards (ed25519)`. Click `I have saved my mnemonic seed safely` and proceed.
Choose a name and password and proceed.
Browse to the [extrinsics](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Ftfchain.test.grid.tf#/extrinsics) , select tftBridgeModule and extrinsic: `swap_to_stellar`. Provide your Bridge substrate address and the amount to transfer. Sign using your password.
Again, a withdrawfee of 1 TFT will be taken, so make sure you send an amount larger than 1 TFT.
The amount withdrawn from TFChain will be sent to your Stellar wallet.
Behind the scenes, following will happen:
- Transferred TFTs from Stellar will be sent from the Stellar vault account to the user's Stellar account
- TFTs will be burned on the TFChain for the transferred amount
