So, your token is being despatched to a brand new blockchain…
Far from an elaborate crypto rip-off, the choice to hold out this course of, generally known as a “token migration” or “token swap,” has turn into more and more fashionable amongst blockchain tasks. Notably, two of the highest 25 cryptocurrencies buying and selling globally – Tron and EOS – are within the midst of such a transition, and a minimum of two extra prime 30 tokens are anticipated to quickly comply with go well with.
With tens of millions – even billions – of dollars value of tokens concerned in every migration, the stakes are excessive. But regardless of this, the blockchain business stays largely uninformed on token migrations and their implications. In a sampling of specialists, CoinDesk discovered that even business leaders have been typically unable to reply primary questions concerning the course of.
Nonetheless, a lot about token migrations might be discerned from these pioneering the shifts. For those that have undergone such transitions, they typically symbolize a troublesome however essential step in realizing their undertaking’s imaginative and prescient.
For Shawn Wilkinson, founding father of decentralized storage startup Storj, which started its token migration in 2017, the rewards merely outweighed the dangers.
He advised CoinDesk:
“The idea is that you just need to rip the band aid off and be on a set of tracks that isn’t going to go off a cliff.”
But why would a challenge want to finish a token migration within the first place?
Often, the shifts are carried out by tasks that start through the use of the ethereum blockchain to boost cash and distribute their tokens. The tokens distributed at this part sometimes act as “placeholders” for these that may ultimately be used when the challenge is reside.
One advantage of this technique is that merchants do not should lock up this capital. Rather, they’re capable of change these placeholder tokens on exchanges whereas they develop their applied sciences.
Therefore, a “token migration” has come to explain the method by which token holders’ balances are transmitted from their ethereum wallets to a given challenge’s new suitable wallets. After the change, tokens have successfully “moved” from one blockchain to a different.
However, it is necessary to notice that token migrations usually are not solely linked to stay blockchain launches, and in addition happen when tasks merely shift from one protocol to a different.
For instance, Storj’s token migration was prompted by its determination to maneuver from a bitcoin-based protocol to ethereum because of scalability points.
“We became increasingly aware that if we didn’t do [the token migration], the consequences would be pretty big,” Wilkinson stated.
How do they work?
For customers and buyers, the diploma of their involvement within the token migration course of varies – sometimes based on the place they retailer their tokens.
For those that retailer their tokens on exchanges, it’s unlikely that they should take any steps to take part within the migration. Major trade Binance, for instance, says it handles “all technical requirements” of the method for the EOS, Tron, ICON and Ontology migrations.
San Francisco-based change Kraken additionally goals to scale back the problem of the method.
“We pause funding ahead of the transition, swap all the old coins for new and when we resume funding, all the old balances are for the new coins,” Kraken co-founder and CEO Jesse Powell defined. “It’s really as simple as that.”
However, customers who retailer their tokens in wallets might have to provoke the method manually.
More particularly, they need to bear token registration, additionally referred to as “mapping,” with a view to ship their tokens from the earlier blockchain to the brand new community.
In apply, this course of sometimes entails producing a project-specific key (for instance, an EOS key) and sending tokens to it from the important thing handle the place the tokens have been initially saved after buy, previous to the mainnet launch (for instance, an ethereum key).
Projects sometimes implement cut-off durations by which customers should swap their tokens. In tasks reminiscent of EOS, these are ‘arduous’ deadlines after which tokens on the previous blockchain can be “frozen” and inaccessible to customers.
Other tasks permit for open-ended migration.
What are the dangers?
But regardless of exchanges’ efforts to simplify token migrations, danger just isn’t solely diminished.
“I don’t think there’s any perfect way to do a token migration,” Wilkinson stated. “It’s always a pain, it’s always miserable, and there’s always, not a small chance, a very hefty chance, that you could screw things up.”
Dialogue with their communities is a method tasks can mitigate a (up to now) widespread drawback: a lack of knowledge amongst token holders.
According to Wilkinson, regardless of initiating Storj’s token migration in 2017, customers are nonetheless migrating their tokens one yr on. Storj has continued to help its token migration, however for tasks with arduous token freeze deadlines, token holders stand to lose their cash if they’re unaware of the migration course of.
Perhaps probably the most vital danger related to token migrations is that they don’t seem to be “trustless” processes.
Instead, customers should place their belief in these answerable for the undertaking to implement the shift in accordance with plan. However, as a result of token migrations are comparatively novel, there’s typically no blueprint for his or her execution.
For this purpose, Wilkinson stated, “A lot of the stuff around the [Storj] migration we built from scratch.”
Though these dangers are not any small matter, they don’t seem to be sudden for such “bleeding edge” applied sciences, he added.
As for what tasks at present enterprise token migrations ought to bear in mind, Wilkinson concluded:
“You have to make a bunch of correct assumptions to get it just right. What I found that worked for us is, we knew where we wanted to go, and we had to have a healthy bit of communication with our community to get them on board with the concept.”
