Improve self-custody

[gabririgo]

Summary

The current RBIP improves existing self custody adapter by removing the free tier and adding a flat 1000 GRG pool holding requirement for transferring tokens to self custody and by allowing transferring any ERC20 tokens.

Motivation

Self custody is a feature aimed at facilitating the life of professional market makers, it is therefore unnecessary for traditional traders. Furthermore, it was first introduced as DEXes did not have enough tokens and volume when compared to CEXes. Uniswap, however, offers the ability to swapping almost any token and has volume approaching 1BN$ per day, with ability of becoming AMM LP. Regarding transferring any tokens, must implement safeTransfer to allow safe transfer of any token.

Specification

• update existing adapter.
• implement safeTransfer (guarantees data.length of transfer is always 2*32 + 4 bytes).
• simplified thresholds.

Thresholds

Transfer Amount (ETH)	GRG required
[ 0 : 9.8696 [	98
[ 9.8696 : 31 [	307
[ 31 : +++ ]	962

Transfer Amount (ERC20)	GRG required
any	1000
